This is problematic. You are putting MINUTES out of normal range. Looking at https://codecogs.com/library/computing/c/time.h/ctime.php?alias=mktime, out-of-range minutes are not documented. Also, see https://stackoverflow.com/questions/20104531/weird-mktime-logic-with-negative-seconds Using out-of-range time fields is not advised. -- Ihor Radchenko // yantar92, Org mode contributor, Learn more about Org mode at <https://orgmode.org/>.
