Where does PBI Service get its Date/Time settings?

[Steve_D]

Hi there, I'm wondering if anyone knows of a setting that tells Power BI Service to use local Date/Time settings. I have Now() function which reports the date a report is refreshed but when it is uploaded to the service the Now() function reports an earlier date (the day before date). I can't see any location settings to instruct the service what date/time reference point to use but, I'm pretty sure the AU service is hosted in Victoria.
