Can you add some test case please ? like https://github.com/iamkun/dayjs/blob/dev/test/parse.test.js#L138 |
includes two tests that would have matched before fix iamkun#1239 but no longer match
|
Added some test cases. The regular expression can still get in trouble accepting odd strings like |
|
LGTM |

we should only match the last But not as a wildcard, this would cause some bug in |

fix #1239
To be sure the last digit token in REGEX_PARSE only matches for milliseconds, the period must be escaped. Otherwise, it acts as a wildcard.
All of these are the same date/time using different ISO 8601 time zone formats:
dayjs("2020-12-31T18:00:00.000-0500")dayjs("2020-12-31T18:00:00-05:00")dayjs("2020-12-31T18:00:00-0500")The first two parse correctly because REGEX_PARSE doesn't match. But the last example does match REGEX_PARSE, with the final
-character matching the wildcard. So the date is parsed in local time and the first three characters of 0500 become 50ms.
