It's because mktime() defaults to the day of current date if the day parameter is omitted. From the manual page for mktime(): "Arguments may be left out in order from right to left; any arguments thus omitted will be set to the current value according to the local date and time."

And as february this year had only 28 days and you're giving it 29, it overflows to march. No bug here.
