Description
The ProductStore has the defaultLocaleString and the defaultCurrencyUomId but does not have a defaultTimeZoneString. What happens when a store is selected (from e-commerce or the pos) is that it will look to the user for a lastTimeZone and if that is not set, it would simply revert to the TimeZone.getDefault() (so the timezone based on the server).
The trouble we had was that you may have an application server that is running in a completely different timezone than what is desired for the store.
I will be attaching a patch to this ticket with changes related to this improvement.
