Timestamp with more flexibility (e.g. nanoseconds, spaces as separators)

[stjugi]

The parser for time-values is more flexible to accept as well formats like:

• time without seconds, e.g. "15:00+01:00"
• space instead of 'T' as date/time separator
• offset without colon, e.g. "+0100" instead of "+01:00"
• comma instead of dot as decimal separator for fractional seconds
• trailing IANA zone id in brackets, e.g. "+01:00[Europe/Berlin]" (as produced by ZonedDateTime.toString()). The zone id itself is stripped and not interpreted; only the offset and local fields are used.
• date-only input (no time component at all) should default to midnight.

Error correction:

• the parsed result must not depend on "now" (e.g. current DST offset) - it only matters that parsing succeeds and the local fields are correct, regardless of when the test is executed.

So you now parse invalid data?

No, only accepting more values during the parsing, allowed according to https://en.wikipedia.org/wiki/ISO_8601 .
