Pay attention to the effects of “?” and “*” in the day-of-week and day-of-month fields!

Note: Support for specifying both a day-of-week and a day-of-month value is not complete (you'll need to use the '?' character in one of these fields).

Be careful when setting fire times between midnight and 1:00am - “daylight savings” can cause a skip or a repeat depending on whether the time moves back or jumps forward.
