When Perl sees \' in a string literal, it places just ' in the string, so you haven't changed anything.

You seem to have missed half of my comment.
I didn't suggest that you escape the 1st and 2nd ' with \.
I didn't suggest that you escape all the ' with \.
I suggested that you escape the 2nd and 3rd ' with \\.

$FileTime = `ssh $ServerName 'perl -e \\'(stat($FP_RemoteFile))[9];\\''`;
executes
ssh $ServerName 'perl -e \'(stat(...))[9];\''
which executes
perl -e '(stat(...))[9];'
on the remote machine if sh behaves as I think it does.

Update: stat($FP_RemoteFile) is also wrong. You need to convert the contents of $FP_RemoteFile into a Perl literal, then you must escape it for sh.
