Timestamp

ROOT
1

Hello,
I am trying to plot data from an ascii file to root. One of the columns of my file is a 64_t timestamp in ps. I need a macro that could change the timestamp into continuous time (to get rid of looping and time repition).
Any suggestions please?
Thank you

If it’s some kind of a simple 64-bit (“unsigned long long int” / “ULong64_t” ?) “timestamp in ps” then it should already be a “continuous time”, shouldn’t it.
If it’s something else, try TDatime and/or TTimeStamp and/or TTime classes.

Thank you for your reply.
What I mean is that the time column in my file as you can see in the attached image (first column) increases to a certain limit then starts again and what I am trying to do is to find some kind of macro or command that would make it increase all the way to the end of file.
