The pattern is a list of six single space-separated fields: representing second, minute, hour, day, month, weekday. Month and weekday names can be given as the first three letters of the English names.
Example patterns:
- "0 0 * * * *" = the top of every hour of every day.
- "*/10 * * * * *" = every ten seconds.
- "0 0 8-10 * * *" = 8, 9 and 10 o'clock of every day.
- "0 0/30 8-10 * * *" = 8:00, 8:30, 9:00, 9:30 and 10 o'clock every day.
- "0 0 9-17 * * MON-FRI" = on the hour nine-to-five weekdays
- "0 0 0 25 12 ?" = every Christmas Day at midnight
