Previous Comments: ------------------------------------------------------------------------ [2019-11-17 21:22:48] obreham at gmail dot com Description: ------------ --- From manual page: https://php.net/function.strftime --- When adding a time interval to 'last Sunday' on a Sunday, you get an incorrect timestamp when interval is longer than a week. 'last Sunday' becomes 'this Sunday'.
