```
#!python
import numpy as np
from ufpy.dataaccess import DataAccessLayer

#Initiate a new DataRequest
request = DataAccessLayer.newDataRequest()
#Set the datatype to grid so it knows what plugin to route the request too
request.setDatatype("grid")

#Use setLocationNames to set the model we want data from
request.setLocationNames('RUC130')
#Next we set the variable and level of data we want
request.setParameters("T")
request.setLevels("850MB")

#getAvailableTimes allows us to query what times are available based off of the
#model, parameter, and levels we have previously identified. These are of the type
#dynamicserialize.dstypes.com.raytheon.uf.common.time.DataTime.DataTime.
t = DataAccessLayer.getAvailableTimes(request)
print t
#Loop through each DataTime object in our returned list and print the RefTime and ValidPeriod
#See dynamicserialize.dstypes.com.raytheon.uf.common.time.DataTime.DataTime for methods available
#with this object
for each in t:
    print each.getRefTime(),each.getValidPeriod()
```

getAvailableTimes() returns a list of !DataTime objects and the print statement above would show something like this:

```

```

There are methods on the !DataTime object to pull out specific information...for example in the loop above we go through each !DataTime object and print out
the !RefTime and !ValidPeriod
