In Mongodb I am storing date and time in ISODate format.
Which looks like this
Time : 01:00
> foo = new Date("2012-07-14T01:00:00+01:00") Sat, 14 Jul 2012 00:00:00 GMT > foo.toTimeString() '17:00:00 GMT-0700 (MST)'
If you want the time string without the seconds and the time zone then you can call the getHours() and getMinutes() methods on the Date object and format the time yourself.
