BCD could be one of many problems, but ASCII strings would me more common in systems I dealt with. There were a lot of assumptions about two digit years that maybe made sense sometime in the 70s for code that you didn’t think would survive more than a few years. Also take a look at struct tm. Its tm_year looked like just a 2 digit year and as such people may format it with printf(“19%02d”,…). It is actually the number of years since 1900. In early 2000 I had to fix a broken ftp server that was sending 19100 as the year. |
