NAME

LocalTime - A wrapper of class DateTime with varied formatters depending on time zone entry

SYNOPSIS

use LocalTime;

DESCRIPTION

LocalTime is a wrapper class holding an instance of the Raku DateTime class. It was created to either add a local timezone (TZ) abbreviation to a time string or show either none or other TZ information depending on the use (or non-use) of the named variable :tz-abbrev. Following are the formatting effects of the various input conditions:

class DateTime

• The default format for DateTime:

  $ say DateTime.new: :2022year;
  2022-01-01T00:00:00Z

class LocalTime

• The default format for LocalTime with no time zone entry:

  $ say LocalTime.new: :2022year;
  2022-01-01T00:00:00 # <== note no trailing 'Z'

• The default format for LocalTime with 'CST' entered:

  $ say LocalTime.new: :2022year, :tz-abbrev('CST');
  2022-01-01T00:00:00 CST

• The format for LocalTime with a non-US TZ abbreviation entered:

  $ say LocalTime.new: :2022year, :tz-abbrev('XYT');
  2022-01-01T00:00:00 XYT

• The format for LocalTime with an empty :tz-abbrev named argument entered:

  $ say LocalTime.new: :2022year, :tz-abbrev;
  2022-01-01T00:00:00 Local Time (UTC -4 hrs)

Note for US TZ entries the user can enter either '*st' or '*dt' (case insensitive) and the correct form will be used for the time of year.

Currently only US abbreviations are in the 'use'd Timezones::US database, but a future modification will add others (perhaps in other languages also). PRs are welcome!
