A cron_string is five fields consisting of the following:
MIN HOUR DAY_of_MONTH MONTH DAY_of_WEEK
The numerical ranges for the fields are as follows:
H Minutes: 0 through 59.
H Hours: 0 through 23.
H Day of the month: 1 through 31.
H Month: 1 through 12.
H Day of the week 0 through 6; Sunday is day 0.
Each field can contain any of the following type entries: a single number, a
comma-separated list of numbers, a hyphen-separated pair of numbers, or an *.
A comma-separated list in a field specifies multiple occurrences for the timed
program to run.
A pair of numbers separated by a hyphen in a field specifies the beginning number,
the ending number, and all the integer numbers in between.
An * in a field means to do it on all occurrences. An exception to the * usage is that
if both the day of the week and the day of the month fields have an *, it just means
every day. If only one of these two fields has an *, that field is ignored, and if
neither has an *, both fields are used.
Example: 0 0,12 * * * specifies a time of midnight and noon every day.
Example: PROG:SEL:TIM:SET 30 * 1,15 5 *,45 17 19 5 *
This sets the times for the timed function at every half past the hour, on the 1st
and 15th of May and again at 1745, May 19th.
Use the PROG:SEL:TIM:ADD <cron_string> command to add new times to
the same named function and use the PROG:SEL:TIM:CLE command to clear all
the times for a named function. If you want other timed functions to run, change the
named function and use the PROG:SEL:TIM:SET command to set a new
cron_string or set of cron_strings for the newly named command.
