Filter events by time of day (time not datetime)

### Problem Statement

I've got a cron job which isn't working properly. I want to check sentry events that are occurring within a time range (no matter the date) e.g. get me all logging that occurs between 05:00 and 06:00 regardless of date.

Correct me if I am mistaken, but the example filters in the docs are asking for a datetime and not a time.

### Solution Brainstorm

Add to the valid filter commands that already exist for time searches: https://github.com/getsentry/sentry/issues/2898 to accept times as well as datetimes.
