Hide timezone from calendar month view?
Ever since a recent update either in iOS or High Sierra (or both) in mid February, all my events in the calendar show the timezone detail right by the time like this : 09:30 UTC-4. But I don't use timezone management (settings are all off on all my devices).
How can I hide this absolutely useless information making my calendar more cumbersome then it already is? I cannot find anyone with this problem or any recent information on this.
iMac, macOS High Sierra (10.13.3)
