I'm not sure what's going on here, but HH is what is being used internally by the cmdlet

time format 24 hour is H 12 hour is h

I get the following for 3:35 PM pacific on a windows 8.1 with PS 5 - wmf 5.0 Preview latest Installed

PS C:\windows\system32> Get-Date -Format FileDateTime
20160115T0335052325

Hmm, seems like a bug in Powershell Cmdlet Get-Date: (it states it is a 24 hour format, but says it will be hhmmssmsms where h is a 12 hour format)

-- FileDateTime - A file or path-friendly representation of the current date and time in local time, in 24-hour format. It is in the form of yyyymmdd + 'T' + hhmmssmsms, where msms is a four-character representation of milliseconds. An example of results when you use this format is 20150302T1240514987.
