[Awaiting feedback] GCAQB8Q Viertelstunden - Event – Challenge

Hi,
I ask for a checker for my GCAQB8Q Viertelstunden - Event – Challenge.
It should be attended for every quarter of an hour, i.e. xx:00, xx:15, xx:30 and xx:45. No matter what hour, day or month. All types of events apply, including your own.
For the output, please output the quarter hours and one event each sorted, for missing events the entry “missing”.
Example:
10:00 missing
12:15 01.07.2016 GC6KRT2 Wochenendstartevent 3 (01. Juli 2016)
13:30 16.12.2018 GC7ZPF2 Meininger Weihnachtsmarkt mit Gospelchor 2018
15:45 20.03.2023 GCA5HJA Kaffepaussi

Thank you for the editing.

As far as I know it is not possible in the system to base a checker on the minutes in an hour. We had this question before but we never came up with a solution

Oops. That amazes me. I can filter by hours regardless of the day or hour, by months regardless of the year or hour, etc.
There are currently only four values ​​for the minutes: 00, 15, 30 and 45. The hourly value is not relevant.
Is it perhaps time-consuming to do four tests on the four minute values ​​and then summarize them?

Please clarify again, I don't know the database: You can't check by minutes, but could you check by hours, e.g. every hour of any day?
