Discrepancy - system time vs Date & Time in Event Viewer: Relevent?

According to MS system time is UTC or "roughly Greenwich Mean Time" (GMT). According to Wikipedia GMT ignores daylight savings time (DST). I live in Belgium which is GMT + 1. Time Zone is set to Brussels, Paris etc and accurate time is shown in Date & Time which is set to account for DST.


Times in Event Viewer show a 1 sec difference between the system time and the time displayed in the Date and Time column, e.g. text in the event description box shows T04:29:52 while Date & Time shows 6:29:53 AM (GMT+1+DST) for system start this morning.


Not sure how discrepancy is occurring but since MS uses time alignment somehow when doing its verify license key thing could this prevent successfully registering my Retail key when I upgrade to Win10? (My system is verified Genuine Windows so I presume this discrepancy has crept in since key validation.)


[Yes, I know a second isn't a lot but since computers run in milliseconds or less and I got an activation error 0x80072F8F after my last fresh install (which synching time didn't fix but updating Windows did) ....]

Hi

It shouldn't make any difference, and you dont actually have to use windows time, other options available, via date and time >> internet times tab >> change settings


As for w10, i'd plump for the using the windows 10 update assistant tool, and the keep my settings option.

Its currently still free

I can only guess but I suspect the different times were acquired independently. As Microsoft doesn't normally document such internal details this could only be determined by examining the Windows source code which is only accessible by authorized individuals. Internally time is maintained and often logged with better precision than what is displayed. The details have changed over the years as computer technology has improved. Two times acquired independently even a microsecond apart could be rounded to a difference of 1 second. It won't happen very often but it is certainly possible.
