Okay, so let's just send timestamp then since it seems to be using that in templeton. That also jives with how we submit events from agent checks, which just require a timestamp.

For your other note, I agree with you that having both a timestamp and date_happened is definitely confusing, but one is used for the Agent case and one for API events. We could consolidate, but we'd still have to support timestamp because we need to be backwards-compatible with event submissions using the older field.
