There is problems when you are developing applications which based on cloud services. That is , time of your service (servers ) are different than the time that your application. If you are using time stamp based data pulling from the cloud service you are in big trouble.
Here if two basic solutions that you can use in those scenarios
1. Use UTC (absolute) Time (highly recommended)
2. Change time zone of the server according to the requirement
Use absolute time you can just do with simple DateTime object.
in C# simply like this
Change Time zone of the Server ( Instances of cloud service )
This is the Task that you cannot find lot of documentation
If you follow following steps You can easily change server time zone ( In azure (cloud) it will randomly create and no one can predict that which instance of the server will run entire service life cycle *Its never happens with cloud) in every running instance once it starting
1. Create batch (*.bat) file with flowing command
Here is time zone reference
2. Add it in to the cloud service ( Not to the cloud service project )
*Add it to project which identifies as role (web, worker) by cloud project . In following example You need to add batch file into WebRole1 project
3. Then R-Click on the batch file and select properties from visual studio . In properties under the Advanced change Copy To Output Directory property in to copy always.
