Did you try searching the forum for "date object"? You'll get a chuckle when you do; this issue has been discussed once or twice. In
this thread I surmised a reason and suggested a stopgap fix (restarting the Max application).
I have had Max open for a long time just now, so I tested the date object to see if my theory was correct, and as I anticipated it reported the incorrect date and time. I restarted the Max application, ran the same test, and it reported the correct date and time. That was with Max 7.0.1 in 32-bit mode in Mac OS 10.8.5.
@Ben Bracken has reopened the issue, so an additional bug report is probably unnecessary, but it can't hurt.
