javascript - get minutes only from iso date time format

Question

I am looking for a way to get minutes only from a date in string (coming from toISOString).

When using Date object, I was using getTime(), but dont think there is a direct method available for ISO format.

Would I need to extract strings directly from ISO format, as its just a string?

Code:

var depTime = new Date(1222332000).toISOString();

This gives me "1970-01-15T03:32:12.000Z", so what is a good way to get minutes which is "32".

`console.log( depTime.split(":")[1] );` Dirty but works for exactly same scenario. — Mohit Bhardwaj, Jul 15 '16 at 16:32
The time value provided ('1222332000') is invalid. This will throw a range error: `VM146:45Uncaught RangeError: Invalid time value` — briosheje, Jul 15 '16 at 16:32
Apologies, mistakenly added single quotes. have removed them. — whyAto8, Jul 15 '16 at 16:35
Yeah, i know, that's real good, but i just had to fix this small issue, so thought will check. I might have to think about using moment now. — whyAto8, Jul 15 '16 at 16:49

You can use getMinutes() from the date object:

var d = new Date('1970-01-15T03:32:12.000Z');
console.log(d.getMinutes());

This is the right method, but, if there are issues with the Time Zone, you can parse the string:

var depTime = new Date(1222332000).toISOString();
console.log(depTime.split(":")[1]);  // 32

That's taking into account TimeZone so it returns `2` for me. – Mohit Bhardwaj Jul 15 '16 at 16:31
@MohitBhardwaj Wow? Seriously? – Praveen Kumar Purushothaman Jul 15 '16 at 16:32

@PraveenKumar some time zones are 30 minutes off. Probably `getUTCMinutes()` would be better. – Pointy Jul 15 '16 at 16:32

Should we use methods from Date object. I have been reading some posts and they say that you should never should Date object, as it could create issues for time zones and client time settings.

@whyAto8 Yes, I get it... Now I have modified. Check it out. – Praveen Kumar Purushothaman Jul 15 '16 at 16:34
@whyAto8 Nopes, in this case, don't use it. – Praveen Kumar Purushothaman Jul 15 '16 at 16:37
Right, its working. Thanks. Just curious, should Date object be used at all, if we have a web app, which takes into account time zones, regional settings etc. Wherever I read, its recommended to use "toISOString()" and if i use that, i would always need to extract minutes, hours, date ,time, like this, would that be right? – whyAto8 Jul 15 '16 at 16:39

You can use

deptime.getMinutes(); // 32

Since it's just a string, regex should work just fine.
