I m using X7. it's exporting with only date when we saved at first time. and when we save at lower file's version then it's exporting fine.
It's not changing date & time automatically.on saving version x7.
Windows 7 files have at least three different dates -- data, date created and date modified.
I'm pretty sure that CorelDraw updates at least one of them every time, though I'm not totally sure its updating the right ones.
