DB Timestamp is not being converted to user time zone

Performed clean install v7.4.3 on Ubuntu 14.03 lts (LEMP stack) for testing. DB Timestamp is not being converted to user defined timezone when selecting popup reminder. However, email reminder timestamp is converted to user defined timezone successfully. This problem does not exist with v7.3.2.

Please Help
