'Windows ISO 8601 timestamp
I need to convert a date in Windows PowerShell to the ISO 8601 format.
In Linux/Unix it was no problem with
TZ=0 date -d "<random-format>" +%Y-%m-%dT%H:%M:%S.000Z
Now I need to do the same in Windows PowerShell. The output format on Windows is

How can I do it?
Solution 1:[1]
PowerShell's Get-Date supports standard .NET time formats. The o round-trip format complies with ISO 8601. Like so,
Get-Date -Format "o"
2017-08-15T12:10:34.4443084+03:00

Get-Date supports Unix formatting strings with the -UFormat parameter. You can reuse it:
Get-Date (Get-Date).ToUniversalTime() -UFormat '+%Y-%m-%dT%H:%M:%S.000Z'

The following works both in Windows PowerShell 5.1 and PowerShell 7.0 on Windows/OS X:
(Get-Date).ToUniversalTime().ToString("yyyy-MM-ddTHH:mm:ss.fffK")
2020-12-01T22:31:41.402Z
If you don't want your milliseconds, then format string would be "yyyy-MM-ddTHH:mm:ss.000K"

Old question but since none of the other answers has it, if you're looking for UTC, this seems to do it:
(Get-Date).ToUniversalTime().ToString("o")
