I put together a quick test of this, just to see how it worked. You can check it out here.

Note that everything is in ZULU/GMT. I'm not doing any conversions. If you are trying to get a time from one of the other drop sites, make sure you are using ZULU/GMT. Currently it only uses an hh:mm format. No seconds.
There may be something here. I'm going to try just a straight grouping next: IE - just grouping Q posts by time to see what drops out of that.
