[Date->AMPM] is an accessor for getting or setting the AM/PM field for a date object.
Getting uses no parameters and returns the AM/PM as an integer.
Setting requires an integer parameter, and supports the =, += and -= operators. Setting modifies the date object in-place, but does not return a value.
Date Object->ampm Date Object->ampm=Integer Date Object->ampm+=Integer Date Object->ampm-=Integer
Use the [Date->AMPM] method. The following example uses a single date object, then gets the AM/PM and returns its value.
Next we set the AM/PM field to a new value using the = operator, then set it again by adding 1 to the AM/PM using the += operator, and set it once more by subtracting 1 from the AM/PM using the -= operator. We return the result for each set operation.
local('d') = date('2011-02-01 08:00:00') #d->ampm + '<br>' #d->ampm=0 #d + '<br>' #d->ampm+=1 #d + '<br>' #d->ampm-=1 #d
0 2011-02-01 08:00:00 2011-02-01 20:00:00 2011-02-01 08:00:00
