Since the default time in the database is in utc, I wanted to be able to still display it in the users correct time. To do this I had to take column :created_at
and
So for my understanding, you need two things:
Localtime/Timezone
You can achieve this by set the right timezone of your rails app, the active_admin will pick up that by default. For example, in your rails config file(config/application.rb):
config.time_zone = 'Eastern Time (US & Canada)'
Default time format
You can refer this Change default date formatter in active admin
Good luck~
