He was comparing HipHop PHP's performance with PHP's and had an initially slower result with HipHop. He profiled the HipHop version and after a few changes, it was still significantly slower than the PHP version. He found that a date or time function was taking about 15-20% of the execution time due to system calls querying the timezone. A simple date_default_timezone_set made the HipHop version take the lead.

Caching the timezone for a minute or so would seem reasonable if it's not already done. I suppose the timezone is never changed on most Debian installs.
