Sreepathi Prasanna commented on OOZIE-1599:
-------------------------------------------
Consolidated the code to retrieve all the available timezones plus the GMT
timeoffsets into one single call in JSONArray and just use this array everytime
the REST call for available Timezone is made. I think there is already a
testcase for this in Testv1AdminServlet class.
> Cache the list of available timezones from the admin servlet

> The admin servlet has a call that returns a list of available timezones. On
> startup, it prepares a list of GMT offsets (e.g. "GMT-12:00", "GMT-11:00",
> etc), which is only generated once. But the rest of the timezones (e.g.
> "America/Los_Angeles", etc) are processed from {{TimeZone}} every time the
> admin servlet is asked for the list.
> We should refactor this to generate/process the entire list either the first
> time its called or at startup and then simply return the {{JSONArray}} when
> the admin servlet is asked for the list.
