PI time expressions can include fixed times, reference-time abbreviations, and time offsets. A time offset indicates the offset direction (either + or -) and the offset amount (a time-unit abbreviation with a value).
For example, PI time expressions can have the following structure:
|
Structure |
Example |
|---|---|
|
Fixed time only |
24-aug-2012 09:50:00 |
|
Reference-time abbreviation only |
t |
|
Time offset only |
+3h |
|
Reference-time abbreviation with a time offset |
t+3h |
Include at most one time offset in an expression; including multiple time offsets can lead to unpredictable results.
