Beware timestamps, though. They usually won't work for dates before
1970 or after 2038. If you suspect you'll need to use dates outside
that period (for example, show the 90 days of <whatever> as of some date
in 1969), your results may be unpredictable.
For example, strftime("%+",0) returns "Wed Dec 31 19:00:00 EST 1969" in
my timezone, and strftime("%+",-1) returns a blank. Yet, doing a
strtotime("1969-12-31 23:59:59 GMT") will get you a -1, and the date()
function appears to support negative timestamps ... which means you
can't skimp on your testing if you decide to go this route. ;-)
