How to change default time zone in azure website service?

It is now possible to change the server time zone for your Azure Websites / Web Apps.

To do this, add an application setting (using the portal) called “WEBSITE_TIME_ZONE” equal to the name of the time zone in question (basically the same string as the key name at HKLM\Software\Microsoft\Windows Nt\CurrentVersion\Time Zones\).

The list of time zone values is here. Use a value from the column labeled "Name of Time Zone".

Changing TimeZone on Azure VMs is not recommended according to Microsoft. Instead convert time to local using methods of TimeZoneInfo structure.

However at least one possible solution is mentioned in the above mentioned post.

P.S. an example of solution provided by question author in comment below:

DateTime timeUtc = DateTime.UtcNow;
TimeZoneInfo kstZone = TimeZoneInfo.FindSystemTimeZoneById("Korea Standard Time"); 
DateTime kstTime = TimeZoneInfo.ConvertTimeFromUtc(timeUtc, kstZone);
