I work 9-5 and switch my PC off when I leave the office each day. When doing timesheets I need to know what time I got to work, so I usually use cmd > systeminfo for finding the System Boot Time.

Since upgrading to Windows 7 however, it's started reporting bizarre numbers between 11pm-2am instead of 8-9am. Today it says it booted at 11:34pm last night!

I checked the event log and there is no entries between when I shutdown at 5:30pm yesterday and booted around 8am this morning.

Has anyone else encountered this?

where are you (what timezone)? sounds as if it's a broken timezone thing -- if it thinks your current hw clock is set to GMT and subtracts to get PST, but your hw clock is actually set to PST, the result will be pretty far off. – quack quixote Oct 7 '09 at 3:50

I see the same thing too on Windows 7. It reports an incorrect system boot time every day after the laptop comes back from sleep mode. The only way I could tell that actual date of when I rebooted my system was to use sysinternal's process explorer and look at the start times for the various system processes. It can't be a broken timezone since the boot time shifts almost every time the system comes out of sleep.

I'm getting the same problem. I hibernate my PC every day. If something is going wrong when resuming, I will obviously notice it because I will lose my current work. My last boot time was on Saturday although I did not start my computer that day! Could anybody help ?

I have the same - Windows 7 x64, since few days after enabling hibernation, after boot the system timer sometimes shows different time.

There's a great writeup here by Joey about what could be the case: Windows XP clock set incorrectly after resume from sleep

I tried setting Windows to auto-sync time, and it seems to have helped... but too little time yet to draw conclusions (I think once it didn't work).

I just had the same issue and found this How can I find out when Windows was last restarted?

It's correct. Command "net statistics workstation" reveals the actual boot time (or near enough to answer the original question).

How about quoting, what you feel, is the relevant information from that answer or flagging this question as a duplicate of that existing question? – Ramhound Apr 20 at 15:42
