Need help with Time Validation in JavaScript

[Megha Vishwanath]

Hi,

We have an application where my clients may be at different timezones.
I need to validate time across the timezones with javascript. The date
object in JavaScript does not allow me to get the timezone.

Any implementation suggestions?

Thanks

-Megha.

The Date Object allows access to the TimezoneOffset of the executing
computer, for the date/time in the Object, assuming the OS is correctly
set. But it knows nothing of remote Timezones and summer time rules.

With an annual exception in Spring, and with allowance for the way (for
example) Germans spell October, time validation is independent of time
location.

But MV may need to validate a remote civil time against a GMT range.

See below, in particular js-date5.htm#DDTA which tests code for reading
Remote Time. Note : at present, the code re-parses TZ for every
conversion; I'm thinking about improving that.

However, if the remote time is local to the remote browser, then
javascript can readily give GMT; if time is in multiple zones, one
should generally use GMT.
