DateOffset

inc - increase, dec - decrease. Time periods:

• Sec
• Min
• Hour
• Day
• Month

DateOffset::incSec($sec = 1, $time = null);
DateOffset::decDay($day = 1, $time = null);

The first parameter is the period(default 1). The second parameter is optional - time, timestamp. If not specified, countdown from now.

DateOffset::incDay(5); // from now, time() + 5 days
DateOffset::decHour(); // 1 hour ago (default 1)
DateOffset::decDay(2, '2020-02-02 20:20:02'); 
// 2020-01-31 20:20:02

DateOffset::offset($sec, $time = null, $negative = false);
