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. The extractor is equivalent to the Datetime::parse(…).

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
