| Update log: | PHP 5.3.0: now relative time format, such as this week, the week before last week, next week, a predetermined one week from Monday to Sunday, instead of back and forth relative to the current date / time of 7 days. PHP 5.3.0: 24:00 now is a valid format. PHP 5.2.7: Prior to this version, if the request for a month in a given date and the date is just the first day of the month, it will increase the time stamp mistakenly returned a week, this point has now been corrected. PHP 5.1.0: If it fails it returns FALSE (before this version returns -1), and increases the E_STRICT and E_NOTICE time zone errors. PHP 5.0.2: now calculated correctly "now" and other relative times based on the current time, instead of the midnight of the time. PHP 5.0.0: Allow microseconds (microseconds but often overlooked). |
