Class CronExpression
- Namespace
- Millrace.Scheduling
- Assembly
- Millrace.dll
A five-field cron expression (minute hour day-of-month month day-of-week) in the
vixie-cron dialect: lists (1,15), ranges (8-18), steps (/5,
8-18/2, 5/15), JAN–DEC and SUN–SAT names, and
0 or 7 for Sunday. When both day fields are restricted (neither is exactly
), the day matches when either field matches — the classic vixie OR rule;
the restriction flags only choose OR-versus-AND, the field masks always apply (so
*/2 in a day field steps as written). Evaluation is UTC-only at minute resolution;
time zones are a later phase.
