If the number of seconds is less than 30 days, it's relative.  If it's
more than 30 days, it's absolute.  This doesn't make lib author's
lives easy from an API perspective, but, on the server side of things,
I've thrown a [+-] character in there to qualify relative vs. absolute
times.  Not especially practical, but satisfies my pedantic need to
explicitly qualify operations.  Blame SmallTalk. -sc
