We have small blog application in Laravel 5.3 in which i need some suggestion about setting time stamps on the following features
1.Admin can able to send notifications to all users with current time stamp (server timezone is Asia/Calcutta) user will see all the notifications based on their time zones.
2.Users can add posts along with their current time stamps , when other users see that posts based on their time zones.
So what are the changes i need to do on the timezone settings in my application??
