Occasionally, you may run into strange date and time representations: they might be represented as a 64-bit integer like this: 636264671350358729.
If you’d like to convert these “ticks” (the smallest time and date increment on Windows), simply convert the number to a DateTime type:
PS> [DateTime]636264671350358729 Thursday, March 30, 2017 10:38:55
Likewise, to turn a date into ticks, try this:
PS> $date = Get-Date -Date '2017-02-03 19:22:11' PS> $date.Ticks 636217465310000000
You could use ticks to serialize date and time in a culture-neutral format, for example.
