I got two timestamps in unix format and I need to find a way to compare them and to find out which one is the newest (closest to present date).
The two timestamps are:
Is there a simple way of doing this in Javascript?

UNIX time is expressed as the number of seconds elapsed since January 1st, 1970, 00:00:00 UTC. Comparison is therefore straightforward: in your example, the second timestamp ( 1300526796 ) is the newest, because 1300526796 (March 19th, 2011, 09:26:36 UTC) is greater than 1299925246 (March 12th, 2011, 10:20:46 UTC).
Comparing Two Dates in JavaScript Another way to compare two dates is by using the built-in getTime() method. The getTime() method returns the number of milliseconds elapsed since the Unix epoch.
Additionally, a TIMESTAMP WITHOUT TIME ZONE value can be compared with a TIMESTAMP WITH TIME ZONE value. All comparisons are chronological, which means the further a point in time is from January 1, 0001, the greater the value of that point in time. The time 24:00:00 compares greater than the time 00:00:00.

Just encountered the same issue, but with multiple timestamps, like so:
1356036198452
1356039026690
1356039067568
1356035166411
In my case, there could be anywhere from 1 to 100 timestamps available.
So the quickest way to get to the "newest" date (in my opinion) would be to do this:
var newestDate = Math.max(1356036198452,1356039026690,1356039067568,1356035166411);
alert(newestDate);
Hope that helps someone out there in the real world.
