// and http://www.php.net/date
//
// thanks to
// - Daniel Berlin <mail@daniel-berlin.de>,
// major overhaul and improvements
// - Matt Bannon,
// correcting some stupid bugs in my days-in-the-months list!
// - levon ghazaryan. pointing out an error in z switch.
// - Andy Pemberton. pointing out error in c switch
//
// input : format string
// time : epoch time (seconds, and optional)
//
// if time is not passed, formatting is based on
// the current "this" date object's set time.
//
// supported switches are
// a, A, B, c, d, D, F, g, G, h, H, i, I (uppercase i), j, l (lowecase L),
// L, m, M, n, N, O, P, r, s, S, t, U, w, W, y, Y, z, Z
//
// unsupported (as compared to date in PHP 5.1.3)
// T, e, o
