!!! Overview
[{$pagename}] is a mess. There are many different formats of [Time] or [DateTime] used within many different systems and some which are the same definition return different or truncated values. There is no consistency and no point of reference that we can find for an explanation.
!! [{$pagename}] [LargeInteger Date]
[LargeInteger Date] is one of the [{$pagename}]s and may be referred to as [FILETIME]
!! [Microsoft Active Directory]
Many attributes in [Microsoft Active Directory] have a [DateTime] type (syntax) called [LargeInteger] which is defined the same as [LargeInteger Date].
Microsoft Active Directory also uses [UTCTime] and [GeneralizedTime] both with the [OID] of [2.5.5.11]
In addition [Microsoft Active Directory] also supports [GeneralizedTime] for __SOME__ [AttributeTypes]:
* [CreateTimestamp]
* [meetingEndTime]
* [meetingStartTime]
* [ModifyTimestamp]
* [WhenChanged]
* [WhenCreated]
* all the msDS-(Attributes that are dates)
* all the msExch(Attributes that are dates)
!! [Microsoft Windows]
[Microsoft Windows] [Operating Systems] use [Windows Time service] for [Time synchronization]
!! MsSQL
But, MsSQL use the [Unix Time] format as I recall.
[Microsoft Windows], the Client [Operating System], counts the number of 100-nanosecond ticks since 12:00 A.M. January 1, [1601|Year 1601] [Coordinated Universal Time] ([UTC]) as reckoned in the [proleptic Gregorian calendar|http://en.wikipedia.org/wiki/Proleptic_Gregorian_calendar| target='_blank' ], __but only returns the current time to the nearest [millisecond]__.
! How to Convert Microsoft Time
From the command-line, on Vista and Windows 7 this worked.
{{{
w32tm /ntte time-as-an-integer
}}}
We also have used the on-line site [Active Directory / LDAP Date Converter|http://www.chrisnowell.com/information_security_tools/date_converter/Windows_active_directory_date_converter.asp|target='_blank']
! [Microsoft] Excel
[Microsoft] Excel stores [DateTime] as [NumericDate] that represents the days since [1989|Year 1989]-12-30. This is also the VB [dateTime].
