roundtrip property

Gets an invariant local date/time pattern which is ISO-8601 compatible, providing up to 7 decimal places of sub-second accuracy which are always present (including trailing zeroes). This is compatible with the BCL round-trip formatting of DateTime values with a kind of 'unspecified'. This corresponds to the text pattern "uuuu'-'MM'-'dd'T'HH':'mm':'ss'.'fffffff". It does not necessarily round-trip all LocalDateTime values as it will lose sub-tick information. Use fullRoundtripWithoutCalendar

Implementation

static LocalDateTimePattern get roundtrip => LocalDateTimePatterns.roundtripPatternImpl;
