Syntax
expression. Bias
expression A variable that represents a TimeZone object.
Remarks
This value is stored as part of the value for TZI for that time zone in the Windows registry. The TZI value is mapped to the Windows TIME_ZONE_INFORMATION structure.
Bias does not take into account any time offset for daylight time or standard time in the time zone. To account for any daylight time offset, use DaylightBias. In general, when the local time zone is adopting daylight time, UTC time is the result of adding the Bias and DaylightBias to the local time. To account for any standard time offset, use StandardBias. In general, when the local time zone is adopting standard time, UTC time is the result of adding the Bias and StandardBias to the local time.
For example, in a state adopting daylight time in the Pacific time zone, the Bias is 480 minutes and DaylightBias is -60 minutes. To determine the time in UTC for June 11, 2 A.M. PST, add a Bias of (480/60) hours and a DaylightBias of -(60/60) hours to the local time June 11, 2 A.M. The time in UTC is June 11, 9 A.M.
