In Perl and PHP, there are no date objects, at least by default. They could
of course be written for use by the IO Element files. In those languages,
I'm just leaving them as a plain string in whatever format they were
received. In Perl and PHP, time is usually handled in the standard UNIX way
as the number of seconds since January 1, 1970 00:00:00, and usually local
time, not GMT. In order to create the number of seconds of the UNIX / C
style date/time struct, a POSIX style string is usually sent to a special
function. For instance, mktime (or gmmktime) in PHP.
int mktime ( [int hour [, int minute [, int second [, int month [, int day
[, int year [, int is_dst]]]]]]])
So in these languages, the raw string argument passed by the JavaScript
IOElement client to the IOElement server script must be processed to break
up the string into the appropriate parameters. So, as long as we use a
4-digit year we should be able to accept any format, and figure out which
order the string is in, be it yyyy/mm/dd or mm/dd/yyyy. But I really hope
to avoid the two and three digit years representative as the "number of
years since 1900" as they are problematic. Anything from 1900-1909 is a 1
digit year, 1910-1999 is a 2-digit year, anything from 2000-2999 is a
three-digit year. What if you wanted something before 1900? The UNIX
timestamp is probably even worse. It's only valid from 1970. On today's
predominantly 32-bit processors, which means 32-bit integers, the timestamp
can only record the number of seconds through 2037 or 2038, I forget the
exact date. (That is likely to be a bigger problem than y2k with archaic
embedded systems. ^^ )
