Date.js 'tt' format doesn't work?

Question

I am using the following javascript code:

var d = Date.parseExact('Jun 4, 2012 12:30:00 AM','MMM d, yyyy h:mm:ss tt');
alert(d.toString('MMM d, yyyy h:mm:ss tt'));

the result of the alert is:

Jun 4, 2012 12:30:00 PM

seems like Date.js doesn't really care about my 'tt' format.... is it a bug??

Thanks.

Answer 1

Not sure if this will apply to you, but I found this today.

As it turns out, the .js file available for download on the main site is a bit out of date. Updating to the version mentioned in this issue fixed a similar issue for me.

Answer 2

First of all it do care if you use the tt format. It seems if you do parse 05:30 AM instead then you get the expected result, but when you go over 12 then it changes into PM.

(You get the opposite result if you start with PM, then you get AM.)

Here I'm a bit on unstable ground as I'm not too familiar with the AM PM system. But isn't those from 00:00 to 11:59?

Anyway seems that's what the Date.js library does, it changes the AM of your 12:30 time to PM.
