HELP! Converting Date Field to Client Timezone using DirectQuery Mode

[bizzybisnette]

Hello I need help on this one as I am not a professional in DAX language yet.

For the previous year I have been using the powerbi desktop in directquery mode to my reporting server.

I store dates in UTC and have been converting them with calculated columns to build my reports.

Here is an example:

EST = DialingResults[Date] - 5/24

This has been working for me until very recently it has stopped in my reports and wont display any data. As of Jan 1/1/2018 which is strangely coincidental because of the new ver of desktop app for Jan 2018. Oddly enough I can look back historically and see data for 2017. 

Here is the format of my date column.

MM/DD/YYYY HH:MM:SS (PM/AM)

I was forced to use a simple function and cannot access alot of functions because of DirectQuery Mode. 

Example:

I also do not have access to the "Table Editor" within my desktop app because of DirectQuery Mode.

Example:

Please help me out guys I would very much appreciate it!

Thanks,
