#Utc clock for desktop windows#
In order to adjust the time on a windows machine, please see these guides: The way you can verify your time zone is correct is by going to one of the global clock sites and checking that the time the website says that your time zone should be is the time you have your computer’s clock set to and that your timezone is matching the time zone you chose to look at. The way the check works is, that we send up a time stamp in GMT ( which is based on the users configured TZ / DST info) if that time is off from the servers view of GMT by more than some margin (+/- 120 seconds) then we send back the “clock off” error to the desktop client. Once the user’s computer is set to the correct time, Hubstaff will track without problems. If the clock off by more than 2 minutes, Hubstaff will not allow the user to record activity.
Hubstaff can calculate this time mismatch because the server knows the correct UTC time and it knows the end user’s time offset (timezone) so it knows if the clock off by more than +/- 2 mins. When a user’s operating system clock is not correct, Hubstaff will display an error telling them that the time on their operating system is off by a certain number of minutes and/or hours which Hubstaff calculates. We recommend that users use NTP (network time protocol) to sync their time to a time server (all OSes offer this) Hubstaff is built to work with your user’s real time zone.
