Both Dr and Mrs Matlock compete in bodybuilding competitions where they show off their flawless physiques, and Mrs Matlock admits that her husband's obsession over fitness and beauty keeps her motivated to look her best.

Each parameter of this function uses the default time zone unless a time zone is specified in that parameter.

Be careful not to use different time zones in each parameter unless that is intended.

See In PHP 5 prior to 5.2.7, requesting a given occurrence of a given weekday in a month where that weekday was the first day of the month would incorrectly add one week to the returned timestamp.

This has been corrected in 5.2.7 and later versions.

For 64-bit versions of PHP, the valid range of a timestamp is effectively infinite, as 64 bits can represent approximately 293 billion years in either direction.

I've had a little trouble with this function in the past because (as some people have pointed out) you can't really set a locale for strtotime.

If you're American, you see 11/12/10 and think "12 November, 2010".

Note: If the number of the year is specified in a two digit format, the values between 00-69 are mapped to 2000-2069 and 70-99 to 1970-1999.

See the notes below for possible differences on 32bit systems (possible dates might end on 2038-01-19 ).

Note: The valid range of a timestamp is typically from Fri, UTC to Tue, UTC.

(These are the dates that correspond to the minimum and maximum values for a 32-bit signed integer.) Prior to PHP 5.1.0, not all platforms support negative timestamps, therefore your date range may be limited to no earlier than the Unix epoch. dates prior to Jan 1, 1970 will not work on Windows, some Linux distributions, and a few other operating systems.
