ramsey/uuid 3.9.3

on PHP Packagist

Fixed

• For v1 UUIDs, round down for timestamps so that microseconds do not bump the
  timestamp to the next second.

  As an example, consider the case of timestamp 1 with 600000 microseconds
  (1.600000). This is the first second after midnight on January 1, 1970, UTC.
  Previous versions of this library had a bug that would round this to 2, so
  the rendered time was 1970-01-01 00:00:02. This was incorrect. Despite
  having 600000 microseconds, the time should not round up to the next second.
  Rather, the time should be 1970-01-01 00:00:01.600000. Since this version of
  ramsey/uuid does not support microseconds, the microseconds are dropped, and
  the time is 1970-01-01 00:00:01. No rounding should occur.
