I guess > its accuracy is determined by the Date's packages accuracy. the accuracy depends on a) date() and mktime() native php implementations for the UnixTS engine b) PEAR::Date for the PearDate engine Anyway, while developing the PearDate engine we discovered a couple of remaining bugs in Pear::Date (fixed in the latest Date release), and the testsuite didn't show other bugs, so I think now Pear::Date is quite trustworthy. Performance-wise, I'd say Harry has written an excellent implementation. By abstracting each date component (years, months, ..., seconds), the php engine has to parse only the pieces you really need, and if you don't need lower-level date components, the class is designed not to calculate them automatically (so no time is wasted on unneeded things) [1] Of course you can use Cache_Lite to reach even higher speed, and IIRC Harry wanted to do some more work on the decorator classes, to make caching the date-related part (as opposed to date calculations + user-land decorator objects as an atomic block) easier.
