generates zones without 30 minute offset.

Currently the timezone list is just generated by square hourly zones. There aren't many 30 minute offset zone's that I'm aware of?? There are also a few 15 minute offset as well. The timezoneList option allows you to pass in your own list.

// with values and labels
[
    { value:'-0500', label: 'Eastern' }, 
    { value: '-0600', label: 'Central' },
    ....
]

// or just values
[ '-0500', '-0600', .... ]

@trentrichardson I come from India :) (GMT +0530). I am currently using the technique you have mentioned and i am happy with it. Just wanted to suggest that it will be better if you could include the 30 minute offsets here.

Check the dev branch, I have hard coded the list of timezones.

The timeZoneString function is broken for 30 and 45 minute offset timezones as well.

In fact I think it's just broken.

var timezone = (off >= 0 ? '+' : '-') + Math.abs(off).toString().substr(1);

substr(1) returns everything but the first character, when I think you're trying to return only the first character? And in the case of 30 and 45 minute offsets you need to return 3.

Edit: Make that 4, and it's also not taking into account needing a 0 before 1-digit hours. It's more complicated than just the first 4 digits.

@ameliaj8 your bug should be fixed in my pull request #424
