Sorry, I was incredibly unclear, mostly because I didn't even know what
I wanted.

[clock seconds] returns a number of seconds. I format those seconds to
my local timezone. Then I remove the TZ designation and pretend that it
is a GMT time. I turn that GMT time into a number of seconds.

Obviously I can do this with string manipulation, I was just wondering
if there was a to do it with [clock], like if it could return how many
seconds from GMT my localtime is. But now that I lay it all out like
that, I realize just how ugly this is (it was a workaround to another
problem). I've since just fixed the issue I was trying to work around
in the first place.

Sorry, everyone!
