I installed osTicket 1.6 RC2. It is not allowing me to change the TimeZone to GMT 5.5 (Bombay....). Everytime I set it, it changes it to GMT 6 (Almaty...). Consequently it shows wrong time (half hour ahead).
I have the same problem when I try it. The config table in the database contains a field 'timezone_offset' which is of the type integer. When the system wants to store 5.5 it automaticly makes it 6.
I will see what can be done to solve this.
