Standardize support for TIME/TIMESTAMP [<precision>] [WITH TIME ZONE] <time string> literals

[johnedquinn]

The PartiQL Kotlin implementation allows for parsing and execution of TIME (2) WITH TIME ZONE '01:02:03.123456+02:03'.

After discussion with the PartiQL Maintainers, this functionality is being propagated to PLK 1.0. This has roots in PostgreSQL. Though, this needs to be formalized.
