I'm using the KLGroup's Chart product, and when applying the same program to the same data on Windows 98 JDK 1.1.7 and Linux JDK 1.1.6v5 (Intel Redhat 5.1), the Linux chart looks very similar, but the time axis (showing dates) is always one day earlier on Linux than the actual data shows. It looks correct under Win98. And yes, both systems have their system clocks set to the correct date. Any ideas why they would behave differently since I doubt it's the JDK version difference...
