The usability is not great: Here is my use case: I have a user in India. She enters a time which should be for an event in Africa. She enters 12:30 pm which is the local time for South Africa. It gets converted to 7:00 am UTC in the database. But actually the event should be at 12:30 pm South African time. But because she is in India, IST time, it got converted to 7:00 am UTC. Now the event is at 9:00 am South African time for whoever is in South Africa and accesses the Strapi admin UI.
I would wish that there is a way to enter local time in Strapi. That would improve a lot the user experience. Right now I have to tell the admin users in the India team to calculate all times in IST from whichever times they get in other timezones. That is a lot of time calculations.
