Hi Enrique,

Is your driver written using asynPortDriver or using native asynManager calls?

If you are using asynPortDriver then is your driver calling asynPortDriver::updateTimeStamp each time you want to update the timestamp?

If you are using native asynManager calls then is your driver calling pasynManager->updateTimeStamp and pasynManager->getTimeStamp each time you want to update and set the timestamp?

You can find examples of using it in the following asyn files:
asyn/testErrrorsApp/src/testErrors.cpp
testAsynPortDriverApp/src/testAsynPortDriver.cpp

There are also examples in all of the areaDetector drivers, for example:

areaDetector/ADExample/exampleApp/simDetectorSrc/simDetector.cpp:

Subject: PV with TSE=-2 and SCAN=I/O Intr returns <undefined> time.

Dear all,
I am working with asynR4-27 on a Linux machine. I have followed the Support for EPICS Time Stamps in asyn (<http://www.aps.anl.gov/epics/modules/soft/asyn/R4-27/AsynTimeStampSupport.pdf>http://www.aps.anl.gov/epics/modules/soft/asyn/R4-27/AsynTimeStampSupport.pdf) but I am still having some troubles.
When I camonitor a PV with TSE=-2 and SCAN=I/O Intr the time obtained is <undefined>, but if I camonitor the same PV with TSE=0 and I/O Intr everything is ok.
I have registered myTimeStampSource with: asynRegisterTimeStampSource(const char *portName, const char *functionName). This is correct, it does not show any error at IOC initialization.
I have coded myTimeStampSource with some printf which are never printed, so maybe it is never being called.
I have registered this function with: epicsRegisterFunction(myTimeStampSource) and added in dbd file, the line: function(“myTimeStampSource”)
Any advice would be highly appreciated.
Thanks in advance.
Enrique Bernal.
