Schedule via cron expression

You can use cron_schedule field to build more precise update checks schedule. A cron expression represents a set of times, using 5 space-separated fields.

Field name	Mandatory?	Allowed values	Allowed special characters
Minutes	Yes	0-59	* / , -
Hours	Yes	0-23	* / , -
Day of month	Yes	1-31	* / , - ?
Month	Yes	1-12 or JAN-DEC	* / , -
Day of week	Yes	0-6 or SUN-SAT	* / , - ?

Month and Day-of-week field values are case insensitive. SUN, Sun, and sun are equally accepted. The specific interpretation of the format is based on the Cron Wikipedia page: https://en.wikipedia.org/wiki/Cron

Predefined schedules

You may use one of several pre-defined schedules in place of a cron expression.

Entry	Description	Equivalent to
@monthly	Run once a month, midnight, first of month	0 0 1 * *
@weekly	Run once a week, midnight between Sat/Sun	0 0 * * 0
@daily (or @midnight)	Run once a day, midnight	0 0 * * *
@hourly	Run once an hour, beginning of hour	0 * * * *

Intervals

You may also schedule a job to execute at fixed intervals, starting at the time it's added or cron is run. This is supported by formatting the cron spec like this:

@every <duration>

where "duration" is a string accepted by time.ParseDuration.

For example, @every 1h30m10s would indicate a schedule that activates after 1 hour, 30 minutes, 10 seconds, and then every interval after that.
