Hours on a visual changing when refreshing on Report server

[Tlotly]

Good day

I have a report with a visual which shows views per hour.  The report works perfectly on desktop version and when I save/publish it on the Report Server:

Desktop version:

The report is scheduled to refreshed every hour on Report Server. So as soon as the scheduled refresh runs, it throws out the other hours, and they will only end on 12pm:

Scheduled refresh:

What causes this and how do can I fix it?

Thank you in advance.

Issues like this are often caused by having code in Power Query that is dependant on the local timezone of the machine running the code and then having the server set with a different timezone to your client machine. So you may want to check if you have any calls doing anything like DateTimeZone.ToLocal and/or check the timezone setting on the server machine.

Thank you for the response. 

I'm not sure if I checked the timezones properly, but I formatted the date to datetimezone. Then created the hours that I'm using on the visual from the same datetimezone date. 

Dax used to create the hour column:

Hours1 = FORMAT([TimeStart - hours - Copy.2],"HH AM/PM")

Date column:

I also checked the format on my machine as well as on the server, it's using the timezone below:

It's still not working after the server refresh, it goes back to showing only 12 hours.

Thank you

Hi @d_gosbell 

Update:

Thank you for the response. It helped a lot as I managed to finally resolve the problem.

Firstly, I changed the format of my date column ( [TimeStart]) on Power Query to datetime. I then created a custom column using my date column i.e. DateTime.ToText([TimeStart],"dd-MM-yyyy HH:mm:ss"). Lastly, I used the custom column to create the Hours column, and it works perfectly.

This is how it's showing now after scheduled refresh on Report Server:

Thanks!
