Returns the time stamp of when the value of strtotime and mktime is 0.

First look at the example

The code is as follows:	Copy code
<? Php $ Time = date ('Y-m-D', strtotime ('00-00-00 00:00:00 ')); Echo $ time; // Output ?>

There is no bug here. 00-00-00 means 2000-00-00. 2000-00-00 is actually, and will be converted to 1999-11-30.
So there are no bugs, and they are completely normal.

Strtotime ('00-00-00 00:00:00 ') is equivalent to mktime.

// Int mktime (hour, minute, second, month, day, and year)
Echo mktime (0, 0, 0, 0, 0 );
The mktime () function is used to obtain the timestamp from the date. If the timestamp is successfully returned, FALSE is returned.
