Numerous time zones which have a 30 or 45 minutes offset are missing

As it is known , Time is an important aspect of trading. It is vital that we set the proper time zone, so that we are able to track different market sessions and the exact time of each session's open and close.

Recently, I found out that some time zones are missing in ATAS platform time zone settings. 

There are numerous time zones which have a 30 or 45 minutes offset, however, as you can see in the following picture, there is no option of choosing these time zone ( E.g. choosing UTC +8:45 is not possible due to the 45 minute offset)

I would be thankful if ATAS's development team consider adding these missing time zone.
Best Regards.
