We have a sharepoint farm with 1 DB server and 2 WFE servers. We as a company have unchecked the DST checkbox on all servers and computers in order to control our time manually with our domain controllers. We do this so we can make DST happen at a certain time as to not interfere with our production. Our sharepoint time is off on list entries and document entries for about half of the year by 1 hour. Recently we changed time again and I set our regional settings from central time (-6) to mountain time (-7) to save an hour (we have to go back an hour because DST pushes us forward an hour in sharepoint and throws everything off). But when I did that, something with a due date of 4/11/2010 would now display as 4/10/2010. Big problem. I think it is because in the background the date is actually stored with the time as 12:00:00 am and when I set the time back one hour the date changes because now it is 11pm on the previous day.
I have tried to edit the timezone.xml but the changes never take effect. Restart IIS, reboot, etc, the timezones are always the same.
I adjust the server clock times but the list item's time doesn't change accordingly.
Where does sharepoint get it's time? and how can I manually adjust it?
How can be released of the bonds of daylight savings and have sharepoint just base its time off of wherever it get its time from?
