A time string format defined by ASN.1 standards. Use this syntax for storing time values in Generalized-Time format.
The format for the Generalized-Time syntax is "YYYYMMDDHHMMSS.0Z". An example of an acceptable value is "20010928060000.0Z". The "Z" indicates no time differential. Active Directory stores date/time as Greenwich Mean Time (GMT). If no time differential is specified, GMT is the default.
If the time is specified in a time zone other than GMT, the differential between the time zone and GMT is appended to the string instead of "Z" in the form "YYYYMMDDHHMMSS.0[+/-]HHMM". An example of an acceptable value is "20010928060000.0+0200". The differential is based on the formula: GMT=Local+differential.
