Specifying Time Expressions
Time expressions use time windows to specify when to change configurations. For more
details on time windows, see “Specifying Time Windows” on page 241.
Time expression syntax
A time expression is made up of the time keyword followed by one or more space-
separated time windows enclosed in parenthesis. Time expressions can be combined
using the
&&, ||, and ! logical operators.
The syntax for a time expression is:
expression = time( time_window [ time_window ...])
| expression && expression
| expression || expression
| !expression
Example
Both of the following expressions specify weekends (Friday evening at 6:30 p.m. until
Monday morning at 8:30 a.m.) and nights (8:00 p.m. to 8:30 a.m. daily).
time(5:18:30-1:8:30 20:00-8:30)
time(5:18:30-1:8:30) || time(20:00-8:30)
