[AWIPS #HSO-864729]: Grid Data History for GFE Type Data

Hi Garrett,

After doing some digging I was able to find access to the model times and the 
data time.
I'm not sure if either of these are really what you want.  I haven't been able 
to find any sort of access to a modification or publish time though.
For the model times, it is one of the optional parameters that can be passed in 
as one of the optional parameters on the request:

req = DataAccessLayer.newDataRequest()
req.setDataType("gfe")

optional = DataAccessLayer.getOptionalIdentifiers(req)
print(optional)

====output====
['parmId.dbId.modelName', 'parmId.dbId.modelTime', 'parmId.dbId.siteId', 
'parmId.dbId.dbType']
==============

values = DataAccessLayer.getIdentifierValues(req, "parmId.dbId.modelTime")
print(values)

====output====
['20200317_0600', '20200317_1700', '20200317_0700', '20200317_1500', 
'00000000_0000', '20200317_0000', '20200317_1200', '20200317_1600', 
'20200317_0900', '20200317_1300', '20200317_1000']
==============

You could then set the model time by calling 
req.addIdentifier("paramId.dbId.modelTime", "20200317_0600") for instance, and 
go from there.

The data time I found by:

response = DataAccessLayer.getGridData(req)
for grid in response:
    data = grid.getRawData()
    lons, lats = grid.getLatLonCoords()
    print('Time : ' + str(grid.getDataTime()))

Anyway, I know these don't exactly answer your question.  I haven't been able 
to find any other time values though as of now.  Let me know if this is helpful 
at all, and I might try and use some other resources to learn more about the 
DAF with relation to GFE data.
Thanks.
