Re: Help understanding DTYP Soft Timestamp

["Johnson, Andrew N. via Tech-talk" <tech-talk at aps.anl.gov>]

The record conversion uses your OS's strftime() routine for everything except the "%f" format conversion. You may need to use %09f for that fractional part though to get the right output — I haven’t checked but I suspect %f will convert a fraction of 1 nanosecond as the string "1" whereas after the decimal point you would need "000000001".

Thanks all for the answers.
I expected something about the formatting, In the example record:

field(INP,  "@%s.%f")

seems to do the work fine but I tried playing with it and didn't get very far. Even though it seems similar to c format strings It doesn't seem to have the same meaning.
Anyway, it works the way it's intended to.

Cheers,

Marco

I would expect to find information about the DTYP="Soft Timestamp" device
support here, or if not here, at least a link to information about it here.

I think it would be good for the reference manual
to be consistent in where it documents fields for each record.

 

Happy to review your pull requests.
