Tried in PS and system startup process and task StartTime is not available:
Get-Process | where {$_.StartTime} | Format-Table Id, StartTime, Name
with or without the StartTime filter, in a unelevated process not in a domain;
an elevated process shows it for all but the System Idle Process.
It is available from WMI as shown by SysInternals ProcExp64 and directly by:
$ wmic process get processid, creationdate, name # rearranged with awk
Proce CreationDate Name

In Cygwin ps, think zero could be subbed by what goes out as /proc/stat btime.
I will try to pull it together and remember how git format-patch and send-email
work. ;^>
