Is gnuplot Y2K compliant?
Gnuplot’s compliance depends in part on the compliance of the underlying operating system and hardware. The only use gnuplot makes of a system- supplied date is in the “set timestamp” command, which simply echos the date on the plot. If the underlying OS cannot produce an accurate time string, then the “set timestamp” command may fail to print the correct date on plots. In gnuplot 3.5, if the user chooses to use %y in a timestamp format, rather than %Y, it will print 2-digit rather than 4-digit years. The effects depend on the importance you place on the timestamps printed on plots. Gnuplot 3.7 also allows the use of time/date data as variables, but the user has complete control over the input format of the data and the output format of the tic labels – the same 2-digit “%y” (interpreted as 1900+) and 4-digit “%Y” formats are both available. But again, these are user-specifiable, so if there is a Y2K problem here, it is the responsibility of the user. Of course, gnuplot is built by exe
