Powershell: get-date & [datetime]::FromFileTime returns different values

HINT: I'm in Greenwich Mean Time, and they get the same result for me.

PS > Get-Date 129442497539436142
10 March 0411 16:55:53

PS > [datetime]::FromFileTime("129442497539436142")
10 March 2011 16:55:53

They produce the same result for me, presumably because I'm in GMT.

(FromFileTime parses the time as UTC, Get-Date appears to be using your local time.)
