Description

Yet and again people gets beaten by timing inconsistency between raw data and the rest of the system, particularly the TPC channel simulation (sim::SimChannel).

MicroBooNE has started some time ago trimming some of their raw::RawDigit collection to save storage space and memory. This requires global counteractions in DetectorClocks configuration.
This approach has two problems:
  • time and again, the changes are forgotten and troubles arise
  • being the approach global, it is possible to have only one of the raw::RawDigit time frames to work correctly, and all the others will be broken.

I propose to add in the event information of where each raw::RawDigit starts in time, with respect to a global reference (ideally, the same as sim::SimChannel TDC counts).

The details of the implementation can vary according to how user-friendly and efficient we want it (that is, which we are more willing to compromise).
