I performed a query on this USGS feature service of Airport locations:

Click for query

And the value for the field LOADDATE is:

LOADDATE: 1411380301000

However, when I pull the layer into ArcMap, the value is:

LOADDATE: 9/22/2014 10:05:01 AM

Does anyone know what the 1411380301000 value represents, and how to convert it back into 9/22/2014 10:05:01 AM?

I asked too quick. According to this thread, the 1411380301000 value is:

...presented as epoch milliseconds since 01/01/1970 GMT.

And I used the following code to convert it:

import time

value = 1411380301000
date = time.strftime('%m/%d/%Y %H:%M:%S', time.gmtime(value/1000.0))

print date

>>> 09/22/2014 10:05:01
