expect fun parse(input: CharSequence, format: DateTimeFormat<LocalDateTime> = getIsoDateTimeFormat()): LocalDateTime(source)

A shortcut for calling DateTimeFormat.parse.

Parses a string that represents a date/time value including date and time components but without any time zone component and returns the parsed LocalDateTime value.

If format is not specified, Formats.ISO is used. 2023-01-02T23:40:57.120 is an example of a string in this format.

See Formats and Format for predefined and custom formats.


if the text cannot be parsed or the boundaries of LocalDateTime are exceeded.
