> 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.
