pt-query-digest reports 'No events processed.' with --since option

[Martin Božič]

I would like to filter events from slow query log to only 4 hours before now, but this doesn't seem to be working no matter what. There aren't any events processed. Processing the whole log without --since option works.

* Complete command‐line used to run the tool: pt-query-digest --database ssio_pro --limit "100%" --since 4h /var/log/slow-query.log

* Tool version: pt-query-digest 2.2.17

* MySQL version of all servers involved: Server version: 5.5.48-MariaDB MariaDB Server

* Output from the tool including STDERR:

---
