Hi Mark,

Thanks. I was trying to figure out if the areaDetector API is backwards compatible (regardless of what TSE is set to). But it does seem to be from reading your document. If a detector driver doesn't call updateTimeStamp(&pImage->epicsTS), then it will just be a zero timestamp presumably (and the record timestamp will be set to zero if TSE=-2). So, it would be harmless, but probably not something that people will do. 

Cheers,
Matt
