This field follows the syntax of cron (with minor differences). Specifically, each line consists of 5 fields separated by TAB or whitespace:

    MINUTE HOUR DOM MONTH DOW

MINUTE | Minutes within the hour (0-59)
HOUR | The hour of the day (0-23)
DOM | The day of the month (1-31)
MONTH | The month (1-12)
DOW | The day of the week (0-7) where 0 and 7 are Sunday.

To specify multiple values for one field, the following operators are available. In the order of precedence,

- '*' can be used to specify all valid values.
- 'M-N' can be used to specify a range, such as "1-5"
- 'M-N/X' or '*/X' can be used to specify skips of X's value through the range, such as "*/15" in the MINUTE field for "0,15,30,45" and "1-6/2" for "1,3,5"
- 'A,B,...,Z' can be used to specify multiple values, such as "0,30" or "1,3,5"

Empty lines and lines that start with '#' will be ignored as comments.

In addition, '@yearly', '@annually', '@monthly', '@weekly', '@daily', '@midnight', and '@hourly' are supported.
