`skewrun` is an Active Directory time discovery toolkit for red teams. It dynamically resolves the Domain Controller's time via network protocols (CLDAP, SMB, NTP, Kerberos, NTLM) and executes commands via `libfaketime` (`LD_PRELOAD`), tricking the executed binary into using the exact DC time.

This solves the Kerberos `KRB_AP_ERR_SKEW` (Clock Skew Too Great) error, allowing you to run tools like Impacket or NetExec from a Linux attack machine whose clock is heavily desynchronized from the target Windows domain, **without requiring root privileges to change the system time**.
