Implement Live HH:MM:SS Timer Display Format

[pushpit21jain]

Problem

The Productivity Tracker includes a study timer, but there is no dedicated requirement ensuring that elapsed time is displayed in a clear and standardized HH:MM:SS format.

While there are existing timer-related issues focused on functionality such as reset buttons, pause/resume controls, and refresh-related bugs, none specifically address the timer's visual formatting and real-time display behavior.

Proposed Enhancement

Implement a live timer display that updates every second and consistently shows elapsed time in the following format:

00:00:00
HH:MM:SS

Examples:

• 00:05:42 → 5 minutes, 42 seconds
• 01:15:30 → 1 hour, 15 minutes, 30 seconds
• 10:05:42 → 10 hours, 5 minutes, 42 seconds

The timer should automatically convert elapsed seconds into hours, minutes, and seconds while maintaining leading zeros for single-digit values.

Features

• Live timer updates every second
• Standardized HH:MM:SS display format
• Leading zero padding for hours, minutes, and seconds
• Accurate conversion from elapsed seconds
• Improved readability for long study sessions

Technical Requirements

• Use JavaScript setInterval() for real-time updates
• Implement zero-padding logic for all time units
• Dynamically update the timer without page refresh
• Ensure accurate hour, minute, and second calculations

Acceptance Criteria

• Timer updates every second in real time
• Time is always displayed in HH:MM:SS format
• Single-digit values include leading zeros
• Hours, minutes, and seconds are calculated correctly
• Timer remains accurate during extended sessions
• Existing timer functionality continues to work as expected

Benefits

• Improves timer readability
• Provides a more professional user experience
• Makes long-duration tracking easier
• Creates a consistent and predictable timer display

Hi @JIYAJAIN30,

I would like to work on this issue under GSSoC 2026.

After reviewing the requirement, I believe the implementation should focus not only on displaying time in HH:MM:SS format but also on maintaining timer accuracy during long-running study sessions.

My planned approach:

• Create a reusable time-formatting utility to convert elapsed seconds into a standardized HH:MM:SS format.

• Implement automatic zero-padding for hours, minutes, and seconds to ensure a consistent display.

• Review the existing timer logic to avoid cumulative timing drift that can occur with repeated interval execution.

• Ensure the display updates smoothly every second without unnecessary DOM re-renders.

• Verify correct behavior for edge cases such as:

  • Less than 1 minute
  • More than 1 hour
  • Extended multi-hour sessions
  • Pause/resume interactions (if supported by the current timer)

• Keep the solution modular so the formatting utility can be reused by future timer-related features.

I will thoroughly test the implementation to ensure readability, accuracy, and compatibility with the existing timer functionality.

Kindly assign this issue to me.

Thank you!
