What are those "indexes"? the indexes that are created when core.splitIndex = true the code that was modified looks for a configuration parameter (or the default) that says something like "2 weeks ago" and that then converts that into a timestamp that can be compared with the modification time for the files that compose that index and then decides to delete anyone that is older than the "expiration date". since time_t is used for the stat.mtime there is a chance that the timestamp might overflow its size, so if an overflow is detected we assume the value to be equivalent to "never" and keep the files. note this scenario will only matter around 2038 and it should be fixed by then as part of the Year 2038 problem if we still care about 32-bit UNIX by then, 32-bit Windows has until next century.
