Bugs Killed

Windows

Workstation clock was several minutes fast and stayed wrong after reboot and time zone changes

The system clock was running about 4–5 minutes fast even after reboots, changing time zones, and with automatic time enabled. The technician forced a time resync and the clock returned to normal.

Killed once by someone from XL.net, on 2026-04-29.

What you see

  • Clock runs about 4–5 minutes fast
  • Time remains incorrect after reboot
  • Changing time zones does not correct the clock
  • Automatic time setting is enabled but the time is still wrong

Why it happens

Likely The device appears to have been updating time from a delayed time source/server.

When it shows up

A Windows workstation shows the clock running several minutes fast or slow even though automatic time is enabled and rebooting or changing time zones does not fix it.

You are in this case if:

  • System clock is offset by several minutes
  • Automatic time is turned on
  • Reboot does not correct the offset
