DateTime#to_json is slow.

Reported by Alex Zepeda | July 10th, 2008 @ 07:34 PM | in 2.x

The DateTime#to_json method is extremely slow. Converting ~6700 AR objects (with two datetime fields each) to JSON takes roughly 18 seconds on a 2.2GHz Core 2 Duo machine.

This patch simplifies the code, avoiding excessive string operations. End result is about a 5x improvement (~18 to ~2 seconds).
