Ramesh Reddy commented on TEIID-3938:
-------------------------------------

EdmDateTimeOffset has Timezone information, but tests are written such that they expected "GMT", but there were series of conversions between default time zone and GMT to make all work. So, I simply removed the GMT for EdmdatTimeOffset and let the TZ set on the object take precedence. For unit tests I introduced system property, to convert back to GMT.

Where as Edm.Date and Edm.TimeOfDay do not have TZ info, so coming in I assumed they are "GMT", while going out converted the time to GMT and then sent it out.  So, I thought the flag is not required here.

> EdmDate and EdmTimeOfDay both assume GMT for incoming string values - however when the convert from Java objects to string they use the local/default Calendar.  So when Teiid is on a server not in GMT date and time value sent via the odata4 translator will likely be wrong.
