Hour not correct
Because of the NTP/SNTP specifications, The Time Server cannot provide Local Time to the network. Time from a Time Server to a PC and time from a PC to any other PC is always provided as universally coordinated time (UTC). UTC has no correction for Time Zone Offset or DST. Each computer has to be configured for the correct Time Zone and DST rule for local time.
If the computer fails to update to the correct hours but the minutes and seconds seem to be correct, then check the computer The time sent from the Time Server to the DC is always UTC (GMT time). Corrections for Local time (Time Zone Offset) and Auto Daylight-Saving Time adjustment must be set at the Date/Time properties screen of the Domain Controller. Click on the time display in the lower right-hand corner of the screen. Adjust the time for the correct Time Zone and place a check in the DST box if your State observes Daylight Saving Time.
