GENPLOT is a PC or UNIX based application for data analysis with essentially no time/date functions and no forced internal structures depending on two byte year representations. Time stamps for files and the few implicit time/date functions are based on the C and FORTRAN standard time() library calls. This raises the following limitations:

PC environment
The epoch is January 1, 1970, with time represented as a 32 bit integer seconds since the epoch. Somewhere in 2038 AD this could potentially be a problem depending on the library implementation. However, should not be a problem until 2106 AD.
UNIX environment
Problem date depends on the epoch. Most implementations are also January 1, 1970 which implies similar target date for concerns.
