Use JavaScript to Parse Time

Question

This is probably something easy, but I'm a bit confused how to do this. How can I, using JavaScript, parse only the time from the following ISO 8601 date string:

 2009-12-06T17:10:00

In other words, with the string above, I'd like to output:

5:10 PM

Any guidance/tutorials on this would be great.

Answer 1

string.slice(11,16) will return 17:10. From there (possibly using slice in more interesting and exciting manners) it should be fairly simple to get it into 24-hour format.

Answer 2

Similar questions have been asked here before. See what-is-the-best-way-to-parse-a-time-into-a-date-object-from-user-input-in-javasc, for example. Or just search for "javascript parse time" and such.

Answer 3

This is so called ISO 8601 format. Mochikit comes with a function to parse it,

http://mochikit.com/doc/html/MochiKit/DateTime.html

You can get a Date object like this,

  timestamp = isoTimestamp("2009-12-06T17:10:00");

Just copy the function if you don't want use Mochikit.

Answer 4

Parsing the ISO timestamp is easy, formatting the time in a culturally appropriate way is hard (5:10 PM is not appropriate for all locales) Many toolkits provide routines for the ISO part, and it's even part of the new ECMAScript 5 standard; only a couple do the latter part, however.

You can try dojo.date.stamp.fromISOString and dojo.date.locale.format.

I believe Date-JS can format times also.
