Assuming local timezone is UTC+7.
Formatting dates:
say gmtime_to_iso8601_date ($timestamp); # => 2018-06-23
say localtime_to_iso8601_date($timestamp); # => 2018-06-24
Formatting times:
say gmtime_to_iso8601_time ($timestamp); # => 19:02:03Z
say gmtime_to_iso8601_time ({tz=>''}, $timestamp); # => 19:02:03
say gmtime_to_iso8601_time ({second_precision=>3}, $timestamp_frac);
# => 19:02:03.456Z
say localtime_to_iso8601_time($timestamp); # => 00:02:03
say localtime_to_iso8601_time({tz=>'+07:00'}, $timestamp);
# => 00:02:03+07:00
Formatting date+time:
say gmtime_to_iso8601_datetime ($timestamp); # => 2018-06-23T19:02:03Z
say gmtime_to_iso8601_datetime ({tz=>''}, $timestamp);
# => 2018-06-23T19:02:03
say gmtime_to_iso8601_datetime ({second_precision=>3}, $timestamp_frac);
# => 2018-06-23T19:02:03.456Z
say localtime_to_iso8601_datetime($timestamp); # => 2018-06-24T00:02:03
say localtime_to_iso8601_datetime({tz=>'+07:00'}, $timestamp);
# => 2018-06-24T00:02:03+07:00
