How to load datetime value from a string in FileDateTime format in powershell?-CodePudding

Get-Date -Format FileDateTime

gives something like this:

20211027T1306219297

Is it possible to import such a string into a datetime variable? Something like?

$date = Get-Date "20211027T1306219297"

CodePudding user response：

You can use [datetime]::ParseExact method with yyyyMMddTHHmmssffff as format argument.

$date = [datetime]::ParseExact("20211027T1306219297", 'yyyyMMddTHHmmssffff', $null)

This is because FileDateTime internally uses yyyyMMddTHHmmssffff format which is documented here.

FileDateTime.

A file or path-friendly representation of the current date and time in local time, in 24-hour format. The format is yyyyMMddTHHmmssffff (case-sensitive, using a 4-digit year, 2-digit month, 2-digit day, the letter T as a time separator, 2-digit hour, 2-digit minute, 2-digit second, and 4-digit millisecond). For example: 20190627T0840107271.
