editeng: fix more 32-bit Time breakage

SfxDateTimeItem and SvxExtTimeField need to use 64-bit integer to store
Time as well.  These classes also have binary serialization
Load()/Save() methods but they are unlikely to be used in a persistent
way, just for the clipboard.

The problem is easy to reproduce in Impress: Insert->Field->Time(fixed)

(regression from 9830fd36)
