DESCRIPTION

Convert dates between ISO and Gregorian formats.

iso

($year, $week, $day) = iso($year, $month, $day);

Returns the ISO year, week and day, when given the year, month, and day, as returned by localtime. (That is, months are zero-based, years are -1900.)

inverseiso

($year, $month, $day) = inverse_iso($year, $week, $day);

Given an ISO year, week, and day, returns year, month, and day, as localtime would give them to you.
