+**CRITICAL:** Implementation MUST follow these principles to avoid over-engineering and maintain simplicity. Violating any of them is a blocking issue — stop and simplify before proceeding.
+
+**No Over-Thinking (Primary Rule):**
+- Do NOT deliberate extensively on simple tasks — act decisively
+- Do NOT speculate about future needs — solve the problem in front of you
+- Do NOT create design documents for single-function changes
+- Do NOT weigh alternatives for more than a few minutes — pick the simplest viable option and implement
+- If a senior engineer would say "just do it", then just do it
+- Over-thinking wastes time; over-engineering wastes code. Both are blockers.
+
+**KISS (Keep It Simple, Stupid):**
+- Simplest correct solution wins. Always.
+- Prefer plain functions over classes, factories, or patterns
+- Prefer constants over config objects
+- Prefer inline code over abstractions for single-use cases
+- If code needs a 5-line comment to explain WHY it exists, it's too complex
+- Fewer lines of code = fewer bugs = easier review
 
 **YAGNI (You Aren't Gonna Need It):**
 - Build only what's needed NOW, not what you might need LATER

+**TDD (Test-Driven Development) — MANDATORY for all code changes:**

+2. **GREEN**: Write the minimum code to make the test pass — nothing more
+3. **REFACTOR**: Improve code quality while keeping tests green
+
+Rules:
+- ❌ NEVER write implementation before tests
+- ❌ NEVER add code without a corresponding test
+- ✅ One test at a time — write, run, repeat
+- ✅ Tests define the spec; implementation satisfies it
+- ✅ If a bug is found, write a test that reproduces it FIRST, then fix
+- ✅ Commit only when all tests pass

+npm run build                           # Ensure compiles

+### Added
+- **Reset timestamp display in local timezone** - The "Resets In" column now shows the actual clock time alongside the countdown (Issue #34):
+  - Short durations: `4h 36m (01:34)` — countdown + local HH:MM
+  - Long durations (≥24h): `6d 16h (Sat 13:48)` — countdown + weekday + local HH:MM
+  - Uses native `Date` local time methods (`getHours()`, `getMinutes()`, `getDay()`) — no external dependencies, no unreliable timezone abbreviations
+
+### Changed
+- `formatResetCell()` in `src/index.ts` now appends local reset time after the countdown portion
+
+### Technical
+- Integration tests updated to use regex assertions (`assert.match`) for timezone-dependent output instead of exact string matching
+- 117 tests passing (0 new tests, 2 updated assertions)

+# Implementation Plan: v1.8.0 Reset Timestamp Display (Local Timezone)
+
+**Version:** 1.0  
+**Date:** June 15, 2026  
+**Branch:** `fix/reset-timer-timezone-34`  
+**Target Version:** 1.8.0  
+**Issue:** [#34 — Display actual reset timestamp in local timezone](https://github.com/guyinwonder168/opencode-glm-quota/issues/34)  
+**PRD Reference:** `docs/opencode-glm-quota-prd-final.md` Section 1.12
+
+---
+
+## Goal
+
+Show the actual reset clock time in the user's local timezone alongside the existing countdown, so users in far-from-UTC zones can plan around resets without guessing when they occur.
+
+## Problem
+
+**Before:** `| ⏱️ 5h Token | 87.0% | ████████████████░░░░░ | 4h 36m |`  
+**After:** `| ⏱️ 5h Token | 87.0% | ████████████████░░░░░ | 4h 36m (01:34) |`
+
+For long durations (≥24h), also show the weekday:  
+`| 📅 Weekly | 17.0% | ████░░░░░░░░░░░░░░░░ | 6d 16h (Sat 13:48) |`
+
+## Design Decisions
+
+| Decision | Choice | Rationale |
+|----------|--------|-----------|
+| Timezone display format | `HH:MM` (local clock time) | Deterministic, user knows their own timezone |
+| Timezone abbreviation | **Not included** | Node.js `toLocaleTimeString` TZ abbreviations are unreliable across platforms (e.g., "GMT+13" vs "NZST") |
+| Long duration format | `Day HH:MM` (e.g., `Sat 13:48`) | Matches issue's proposed format for weekly resets |
+| API for local time | `getHours()`, `getMinutes()`, `getDay()` | Follows existing `date-formatter.ts` pattern, no dependencies |
+| Testing approach | Regex assertions in integration tests | Timezone-dependent output made deterministic via pattern matching |
+
+## Impact Analysis
+
+### Files MODIFIED
+
+| File | Changes |
+|------|---------|
+| `src/index.ts` | `formatResetCell()` — add local time display after countdown |
+| `tests/integration/reset-time-display.test.ts` | Update assertions: `includes` → `match` with regex for time pattern |
+| `package.json` | Version: `1.7.0` → `1.8.0` |
+| `sonar-project.properties` | `sonar.projectVersion`: `1.7.0` → `1.8.0` |
+| `CHANGELOG.md` | Add `[1.8.0]` entry |
+| `README.md` | Update feature bullet + output example |
+| `docs/opencode-glm-quota-prd-final.md` | Add Section 1.12 |
+
+### Files UNCHANGED
+
+| File | Reason |
+|------|--------|
+| `src/utils/reset-timer.ts` | Long-form `formatTimeUntilReset()` not used in Markdown table, separate concern |
+| All other `src/` files | No output or logic changes needed |
+
+---
+
+## Implementation Slices
+
+### Slice 1: TDD RED — Update integration test assertions
+
+**Goal:** Write failing tests that describe the desired new format.
+
+**Changes to `tests/integration/reset-time-display.test.ts`:**
+- Short duration test: `includes('| ... | 4h 42m |')` → `match(/\| ... \| 4h 42m \(\d{2}:\d{2}\) \|/)`
+- Long duration test: `includes('| ... | 4d 12h |')` → `match(/\| ... \| 4d 12h \([A-Z][a-z]{2} \d{2}:\d{2}\) \|/)`
+- MCP test: Unchanged (no reset time → still `—`)
+
+**Verify:** `npm run test -- tests/integration/reset-time-display.test.ts` → 2 failures (RED)
+
+---
+
+### Slice 2: TDD GREEN — Modify `formatResetCell()`
+
+**Goal:** Minimum code to make tests pass.
+
+**Changes to `src/index.ts` `formatResetCell()` (was lines 283-301):**
+
+```typescript
+function formatResetCell(resetTime?: number): string {
+  const resetAt = asNumber(resetTime);
+  if (resetAt === null) return '—';
+
+  const diffMs = resetAt - Date.now();
+  if (diffMs <= 0) return '—';
+
+  const totalMinutes = Math.floor(diffMs / (1000 * 60));
+
+  // Format countdown portion
+  let countdown: string;
+  if (totalMinutes >= 24 * 60) {
+    const totalHours = Math.floor(totalMinutes / 60);
+    countdown = `${Math.floor(totalHours / 24)}d ${totalHours % 24}h`;
+  } else {
+    countdown = `${Math.floor(totalMinutes / 60)}h ${totalMinutes % 60}m`;
+  }
+
+  // Format local reset time portion (Issue #34)
+  const resetDate = new Date(resetAt);
+  const hh = String(resetDate.getHours()).padStart(2, '0');
+  const mm = String(resetDate.getMinutes()).padStart(2, '0');
+
+  if (totalMinutes >= 24 * 60) {
+    const dayNames = ['Sun', 'Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat'];
+    return `${countdown} (${dayNames[resetDate.getDay()]} ${hh}:${mm})`;
+  }
+
+  return `${countdown} (${hh}:${mm})`;
+}
+```
+
+**Verify:** `npm run test -- tests/integration/reset-time-display.test.ts` → all pass (GREEN)
+
+---
+
+### Slice 3: Full test suite verification
+
+**Goal:** Ensure no regressions.
+
+**Verify:** `npm test` → 117 tests pass, 0 failures
+
+---
+
+### Slice 4: Documentation + version bump
+
+**Tasks:**
+1. `package.json`: `1.7.0` → `1.8.0`
+2. `sonar-project.properties`: `sonar.projectVersion` `1.7.0` → `1.8.0`
+3. `CHANGELOG.md`: Add `[1.8.0]` entry under `[Unreleased]`
+4. `README.md`: Update feature bullet + output example
+5. `docs/opencode-glm-quota-prd-final.md`: Add Section 1.12
+
+**Verify:** `npm run build && npm run lint && npm test` all pass
+
+---
+
+## Execution Order
+
+```
+Slice 1 (RED tests)
+    ↓
+Slice 2 (GREEN implementation)
+    ↓
+Slice 3 (full suite verification)
+    ↓
+Slice 4 (docs + version bump)
+```
+
+All slices are sequential — small scope, no parallelism needed.
+
+## Risk Assessment
+
+| Risk | Mitigation |
+|------|------------|
+| Timezone-dependent test output | Regex assertions (`\d{2}:\d{2}`) instead of hardcoded times |
+| Cell width increase | "Resets In" column is last, Markdown tables auto-size — no alignment issues |
+| DST transitions | `getHours()`/`getMinutes()` always return local time per system TZ — correct by design |
+| Node.js version differences | Using standard `Date` methods available since ES1 — universally supported |
+
+## Estimated Effort
+
+| Slice | Files | Time |
+|-------|-------|------|
+| Slice 1 | 1 | 10 min |
+| Slice 2 | 1 | 10 min |
+| Slice 3 | 0 | 5 min |
+| Slice 4 | 5 | 20 min |
+| **Total** | **7 files** | **~45 min** |

+### 1.12 Reset Timestamp Display in Local Timezone (COMPLETED - v1.8.0 ✅)
+
+**Problem Statement:**
+
+The reset timer only shows a **countdown** (`4h 36m`), but not the **actual reset timestamp**. For users in timezones far from UTC (e.g., UTC+12 Pacific/Auckland), the 5-hour rolling window reset often happens at an inconvenient local time (e.g., 1–2 AM), and it's not obvious *when* exactly the quota will reset (Issue #34).
+
+**Solution:**
+
+Show the actual reset time in the user's local timezone alongside the countdown:
+
+```
+| ⏱️ 5h Token | 87.0% | ████████████████░░░░░ | 4h 36m (01:34) |
+| 📅 Weekly    | 17.0% | ████░░░░░░░░░░░░░░░░ | 6d 16h (Sat 13:48) |
+```
+
+**Design Decisions:**
+
+| Decision | Choice | Rationale |
+|----------|--------|-----------|
+| Timezone display format | `HH:MM` local clock time | Deterministic, user knows their own timezone |
+| Timezone abbreviation | Not included | Node.js `toLocaleTimeString` TZ abbreviations unreliable across platforms |
+| Long duration format | `Day HH:MM` | Matches issue's proposed format for weekly resets |
+| API | `Date.getHours()`, `getMinutes()`, `getDay()` | Native methods, no dependencies, follows existing `date-formatter.ts` pattern |
+
+**Implementation:**
+
+- `formatResetCell()` in `src/index.ts` computes local time from `nextResetTime` Unix timestamp
+- Short durations (`<24h`): Returns `${countdown} (${HH}:${MM})`
+- Long durations (`≥24h`): Returns `${countdown} (${DayName} ${HH}:${MM})`
+- MCP rows without `nextResetTime`: Unchanged (`—`)
+
+**Testing:**
+
+- Integration tests use regex assertions (`assert.match`) for timezone-dependent output
+- Pattern: `/\d{2}:\d{2}/` for short durations, `/[A-Z][a-z]{2} \d{2}:\d{2}/` for long durations
+- Works deterministically across CI environments (GitHub Actions defaults to UTC)
+
+**Status:** ✅ COMPLETED (2026-06-15) - v1.8.0, resolves Issue #34
