mkornatzki 2008-06-27 08:44 reporter ~0018202	with the patch i post in 0009272:0018136 i didn't have these problems. maybe you can try it.

Blue Ninja 2008-06-27 10:27 reporter ~0018204	I think this is due to bug 0009140 - a blank due date gets defaulted to 1970-01-01 instead of null, and then gets adjusted by the time zone. You're getting 1969-12-31 because you must be ahead of GMT (so the difference gets subtracted). And since this causes it to be "changed", MAntis logs the history of changes.

vboctor 2008-07-13 16:25 manager ~0018464	We also need a database upgrade step that deletes all these bogus entries. For example, delete all due date history entries that are smaller than year 2000.
