time

As far as I am aware, there are 3 ways to check the computer boot time in windows. And they should give the same time, just in different formats. Why do I get different times, where do these commands get their time?

wmic os get lastBootUpTime | find "+120"
20140823002317.596695+120

systeminfo | find /i "boot time"
System Boot Time:          23.8.2014, 0:23:17

net statistics server | find /i "statistics since"
Statistics since 22.8.2014 18:21:30

The first two are the same (0:23), but the third is different (18:21), and also accurate. Why? At boot, all tree show the same, but at some point, they change.

I am using windows 7 ultimate, 64bit.
