relnote(121): Date.parse fixes and additions

[vinnydiehl]

Entry

• Date.parse() now accepts several additional date formats:

  • Year > 9999 for YYYY-MMM-DD format (e.g. 19999-Jan-01)

  • MMM-DD-YYYY (e.g. Jan-01-1970)

  • Milliseconds for non-ISO date formats (e.g. Jan 1 1970 10:00:00.050)

  • Day of week at the beginning of formats which were being rejected, such as:

    • Wed, 1970-01-01
    • Wed, 1970-Jan-01

    The day of week does not need to be correct, or a day of week at all; for example, foo 1970-01-01 works.

• Other Date.parse() fixes:

  • YYYY-M-DD and YYYY-MM-D are no longer assumed GMT as an ISO date YYYY-MM-DD would be
  • Milliseconds for all formats are truncated after 3 digits, rather than being rounded

Does this also have corresponding docs updates required? See #30235 (comment)

Even though there are quite a few associated bugs, I think it'd be helpful to link each element in your list to the relevant Bugzilla ticket. WDYT about adding that context to your list?

Added relevant Bugzilla links - thanks!
