With GMT being 4 hours different from our location, when trying to provide usage statistics and summaries on apps being used in ArcGIS Online, it would be far more valuable if I could pick our time zone instead of saying when I hand over the screen of the charts "it's 4 hours ahead, so 8am is Noon". It's fine if the overall reporting for usage defining a day is midnight-11:59 GMT, just the ability for a translation for local reports would be very valuable.
