Detailed cron expression
a cron expression of at least 6 (and possibly 7) has time elements separated by spaces. By order:

Sec (0 to 59)
min (0 - 59)
3 hours (0 to 23)
four days (0 to 31)
May (0 to 11)
6 weeks (1 ~ 7 1 = SUN or SUN, MON, TUE, WED , THU, FRI, SAT)
Year (1970-2099)
in which each element can be a value (e.g., 6), a continuous section (9-12), a time interval (8-18 / 4) (/ indicates every 4 hours), a list of (1,3,5), the wildcard. As the "day of the month" and "date of the week," these two elements are mutually exclusive, and must be for one of the settings. Instance:

Executed once every 5 seconds:? / 5 * * *
every one minute to perform a:? 0/1 * *
00 * * 10,14,16 day 10:00, 14:00, 4:00?
