Description

In artdaq, we commonly use filenames of the form artdaqdemo_r%06r_sr%02s_%to_%#_dl1.root. However, in recent art versions, this causes automatically-opened files to keep index 1 while incrementing the timestamp field instead:
artdaqdemo_r000007_sr01_20180314T143646_1_dl1.root
artdaqdemo_r000007_sr01_20180314T143655_1_dl1.root
artdaqdemo_r000007_sr01_20180314T143705_1_dl1.root
artdaqdemo_r000007_sr01_20180314T143715_1_dl1.root
artdaqdemo_r000007_sr01_20180314T143725_1_dl1.root

We would like a timestamp variable which tracks the start of the run time, so that these would become something like:
artdaqdemo_r000007_sr01_20180314T143646_1_dl1.root
artdaqdemo_r000007_sr01_20180314T143646_2_dl1.root
artdaqdemo_r000007_sr01_20180314T143646_3_dl1.root
artdaqdemo_r000007_sr01_20180314T143646_4_dl1.root
artdaqdemo_r000007_sr01_20180314T143646_5_dl1.root

There are a couple different ways we could do this:

  1. Use the timestamp in the (Sub)RunPrincipal, or
  2. Capture the time whenever the output module's begin(Sub)Run functions are called.

We argue 1 is probably the best-defined option. Did you have any other possibilities in mind?

I would tend to agree with your analysis. Ideally, the Principal, the file name, and the SAM metadata would all always be in agreement...

The following file-renaming patterns have added:

Specifier Meaning
%ts Start time of SubRun with lowest ID
%tS Start time of SubRun with highest ID
%tr Start time of Run with lowest ID
%tR Start time of Run with highest ID
The time recorded corresponds to the time at which the output module begins processing the beginning of the (sub)run.
