> CommitlogArchiver only has granularity to seconds for restore_point_in_time

> Commitlog archiver allows users to backup commitlog files for the purpose of
> doing point in time restores. The [configuration
> file|https://github.com/apache/cassandra/blob/trunk/conf/commitlog_archiving.properties]
> gives an example of down to the seconds granularity but then asks what
> whether the timestamps are microseconds or milliseconds - defaulting to
> microseconds. Because the [CommitLogArchiver uses a second based date
> format|https://github.com/apache/cassandra/blob/trunk/src/java/org/apache/cassandra/db/commitlog/CommitLogArchiver.java#L52],
> if a user specifies to restore at something at a lower granularity like
> milliseconds or microseconds, that means that the it will truncate everything
> after the second and restore to that second. So say you specify a
> restore_point_in_time like this:
> restore_point_in_time=2024:01:18 17:01:01.623392
> it will silently truncate everything after the 01 seconds. So effectively to
> the user, it is missing updates between 01 and 01.623392.
> This appears to be a bug in the intent. We should allow users to specify
> down to the millisecond or even microsecond level. If we allow them to
> specify down to microseconds for the restore point in time, then it may
> internally need to change from a long.
