parse static method

JDate parse(String string)

Constructs a new JDate instance based on string.

The string must not be null. Throws a FormatException if the input string cannot be parsed.

The function parses a subset of ISO 8601 which includes the subset accepted by RFC 3339.

The accepted inputs are currently:

• A date: A signed four-to-six digit year, two digit month and two digit day, optionally separated by - characters. Examples: "13770101", "-0004-12-24", "1600-04-01".
• An optional time part, separated from the date by either T or a space. The time part is a two digit hour, then optionally a two digit minutes value, then optionally a two digit seconds value, and then optionally a '.' or ',' followed by at least a one digit second fraction. The minutes and seconds may be separated from the previous parts by a ':'. Examples: "12", "12:30:24.124", "12:30:24,124", "123010.50".
• An optional time-zone offset part, possibly separated from the previous by a space. The time zone is either 'z' or 'Z', or it is a signed two digit hour part and an optional two digit minute part. The sign must be either "+" or "-", and can not be omitted. The minutes may be separated from the hours by a ':'. Examples: "Z", "-10", "+01:30", "+1130".

This includes the output of both toString and toIso8601String, which will be parsed back into a DateTime object with the same time as the original.

The result is always in either local time or UTC. If a time zone offset other than UTC is specified, the time is converted to the equivalent UTC time.

Examples of accepted strings:

• "1387-02-27"
• "1387-02-27 13:27:00"
• "1387-02-27 13:27:00.123456789z"
• "1387-02-27 13:27:00,123456789z"
• "13870227 13:27:00"
• "13870227T132700"
• "13870227"
• "[phone]"
• "1387-02-27T14Z"
• "1387-02-27T14+00:00"
• "-123450101 00:00:00 Z": in the year -12345.
• "1387-02-27T14:00:00-0500": Same as "1387-02-27T19:00:00Z"

Implementation

static JDate parse(String string) {
  string = string.numbersToEnglish().replaceAll(RegExp(r'[/\\]'), '-');
  final date = DateTime.parse(string);

  if (date.isUtc) {
    return JDate.utc(
      date.year,
      date.month,
      date.day,
      date.hour,
      date.minute,
      date.second,
      date.millisecond,
      date.microsecond,
    );
  } else {
    return JDate(
      date.year,
      date.month,
      date.day,
      date.hour,
      date.minute,
      date.second,
      date.millisecond,
      date.microsecond,
    );
  }
}
