JavaScript TimeStamp into MilliSeconds

javascript date timestamp

12,822

parse(): Returns the number of milliseconds since midnight 1 January 1970 for a given date and time string passed to it.

var milliSeconds = Date.parse('09-MAR-11 04:52:43:246000000 AM');

In your datestring please change the hour/min/etc separator to : instead of ., so JS can recognize correctly the date.

I have only tested this on Google Chrome. Please try out my jsFiddle Demo in your browser. The range of date formats that are recognized might differ between browsers.
