Trying my best to be earnest. Could we get a Feature Request sub forum wherever it's most appropriate? I'll start.
24 hour clock setting please and thank you.
Just post your ideas here in the general forum. Don’t expect any sort of feedback from anyone at Niantic and don’t expect them to implement anything either. They seem pretty content on mostly ignoring these forums and also, giving us what they want. Good luck
Lots of players play on 24 hour clock setting, including me.
Not sure how to change it though
If your phone language is English (US), change it to English (UK). The locale comes with 24h time and day/month/year date format. Android, don't know if apple has similar setting.
That would require Niantic to pay attention to the forums.
