datetime
The datetime extractor parses the input into a timestamp. The format of the target needs to be specified as a parameter to the extractor.
Predicate
When used with ~
, the predicate parses if the target can be parsed to a nanosecond-precision timestamp. The predicate will fail if it encounters any of the errors described in the Error section below.
Extraction
If the predicate parses, the extractor returns the 64-bit nanosecond-precise UTC UNIX timestamp.
Example
match { "test" : "2019-01-01 09:42" } of
case foo = %{ test ~= datetime|%Y-%m-%d %H:%M| } => foo.test
default => "ko"
end;
## output: 1546335720000000000
Errors
The extractor will fail due to one of the following:
- Incorrect input is passed
- Input doesn't match the format passed
- Input doesn't contain the Year, Month, Day, Hour & Minute section irrespective of the format passed.
- Input contains more components than the format passed
