Looking at /api/documentation, I notice that date/time filter parameters are defined like this:
Date filters: &filter=field:start value|end value (using datetime format)
But there doesn't seem to be any specification anywhere in the API documentation that actually defines exactly what the "datetime format" is.
Looking at some of the search results, it seems like the format might be similar to ISO 8601. E.g.:
Is this the proper format? If so, what time zone is it defined as? This seems like something that would be great to add to the API documentation if possible.
