Ranges
You can specify a range within square brackets [ ]. For Example:, to define a range between Monday and Wednesday you can write one of the following:
[mon, tue, wed]
[mon to wed]
[mon - wed]
[mon wed]
It is possible to specify the start or end of a range as non-inclusive by turning the brackets. For Example: if you want to express "the first 30 minutes of every hour" you can write:
($minute in [0 to 29]) or
($minute in [0 to 30[)
The following variants are possible:
[Start to End]
[Start to End[
]Start to End]
]Start to End[
In set operator
The In set operator is used check whether an element is included in a set of elements.
in set {element-1, element-2, element-3 ... element-n}
Example:
($weekday in set {mon, wed, fri})
Mod operator
The Mod operator is used for defining time predicates such as “every third week”, “odd weeks” or “even weeks”. Since week numbers in the system start with 0 you would express “every odd week” by writing:
($week mod 2)
Logical operators
You can use logical operators when you combine several time predicates.
Not (time predicate)
And (time predicate)
Or (time predicate)
Example:
timepredicate = "((($weekday in [mon to fri]) and ($hour in [08 to 18[)))";
