[Gnuplot-info] strptime() fails to recognize negative hours

[Sergei N. <vo...@ra...>]

Hi!
posting a question on https://stackoverflow.com/questions/60985800/reading-formatted-column-in-gnuplot it came out that strptime() does not recognize 
negative sign in cases like the following:

gnuplot> myTimeFmt = "%tH:%tM:%tS"
gnuplot> print strptime(myTimeFmt,"-00:24:25.3")
1465.3
gnuplot> print strptime(myTimeFmt,"00:-24:25.3")
-1465.3
gnuplot> 

Is there a bug or it should work like this? If it does, how one would take 
this minus into account?

Thanks,
Sergei
