The official minecraft documentation has renamed the play_one_minute statistic to play_time since 1.17 update.

See the update list at the bottom of this page: https://minecraft.fandom.com/wiki/Statistics

So why play_time is not present ? Can you add it too please ?

NB: I think you should keep play_one_minute as well, because from what I could see if a player has not logged in since the update the stats file does not contain the play_time statistic.
