Hope that helps!
Thought I'd make the ST clearer. Basically, you start with a map statement which takes every line in your file and puts it in an anonymous array with the timestamp (via split). Then, it passes an array with each of these to the sort routine, which sorts them based on the timestamp by getting that info from each anonymouss array in turn. Finally, the map statment at the end transforms this array of anonymous arrays back into an array with the lines from the file, properly sorted. Tada!
You could also try a GRT, which might look something like this:
This has the clear limitation that it sorts asciibetically rather than numerically (doing it numerically might mitigate the benifits of GRT over ST, I'm not sure), which shouldn't be a problem really with time() but might be something to watch out for. Also, I'm sure this should have been done with pack or some such nonsense, but I don't know how. And finally, it may not even be faster. But, TMTOWTDI.
