Extracted timestamps are wrong #334
Description
libdatadog specifies that sample timestamps mark the end of the event. Ours mark the beginning. This should probably be fixed, although I'm not 100% sure how to do this in a general way.
- For timelike events, this is clear
- For events in which durations must be extrapolated, this is slightly unclear for lack of examples.
Not really fixing because it doesn't seem to me that there's a big difference between estimating our CPU time stimates as forward or backward durations (I think????)
