Thomas Guillemard 708620252e ITimeZoneService rewrite (#722)
* Clean up ITimeZoneService

Add error codes and simplify parsing

* Add accurate timezone logic

TOOD: LoadTimeZoneRule and location name cmds.

* Integrate the new TimeZone logic

* SCREAMING_UNIX_CASE => PascalCase

* Address comments

* Reduce use of pointer in the LoadTimeZoneRule logic

* Address comments

* Realign tzIfStream logic in LoadTimeZoneRule

* Address gdk's comments
