Would you please also implement a 'secure login' feature for the login page?
(a simple login but with httpS)

By the way, Istanbul is listed as 'Europe/Istanbul' in http://mylittleforum.net/demos/time_zones/time_zones_complete but also as 'Asia/Istanbul' in the reduced list: http://mylittleforum.net/demos/time_zones/time_zones

It usually is listed as 'Europe/Istanbul'
ref: http://www.timezoneconverter.com/cgi-bin/zoneinfo.tzc?s=default&tz=Europe/Istanbul
ref: http://www.travelmath.com/time-zone/Europe/Istanbul

The time zone abbreviation for Istanbul is: EET - Eastern European Time.

Kind regards
