I can't see what I'm doing wrong. I'm subtracting 60*60*24 from a unix

Try doing this instead:

$unixtime2 = strtotime("-1 day", $unixtime);

I couldn't see what you were doing wrong in your code from a quick
glance,
but the above way is easier to read anyway.

Thanks that really helped a lot, five minutes to fix what I've been
banging my head against all night. Funny thing is that code worked fine
for a year and it still works for most dates but it hit that one date and
didn't work right.

I had the same effect when clocks were turned +1 hour to daylight saving
time on March 26th here in Finland. I had two dates of which one was in
normal time and another that was in daylight saving time and I kept
wondering why the difference between them is was 5 days and 23 hours or
something like that, until the whole daylight saving thing finally dawned to
me. I fixed it by using GMT times which are not affected by DST.
