Remove header from output of pipeline

Question

I am trying to get the update time of the most recent .vhd in a folder.  I have:
get-childitem "*.vhd" | sort-object LastWriteTime | Select-Object LastWriteTime
My issue is I am trying to get rid of the header.  How do I do that?  I tried the option with format-table but was not able to set the result to a variable in a script.
$testme = get-childitem $dstPath\$guestName\*.vhd | sort-object LastWriteTime | Format-Table -HideTableHeaders  LastWriteTime
writehost $testme

Answer 1

This usually works, sometimes doesn't:
get-childitem "*.vhd" | sort-object LastWriteTime | Select-Object -ExpandProperty LastWriteTime
The 'ExpandProperty' parameter is supposed to be used for expanding properties that are collections, but if the property is a scalar value it will just print it out without the header. Odd, but works.
A more direct way is:
get-childitem "*.vhd" | sort-object LastWriteTime | ForEach-Object {$_.LastWriteTime}
