Conquest and UIDs

Hi,

Conquest uses the UIDPrefix in dicom.ini. The windows GUI inititalises it as:

'1.2.826.0.1.3680043.2.135.' + IntToStr(t.Date) + '.' + IntToStr(t.Time);

Where "1.2.826.0.1.3680043.2.135" is the root provided to NKI

I.e. the install date and time (in ms) makes each server unique, with a very limited change of collision.

The linux install does not do this!

From there, uids are generated as follows:

Append . and one digit(6 or 7 depening on source file) and then:

#ifdef WIN32

sprintf(oString, "%s.%u.%d.%u", UIDPrefix, (unsigned int)time(NULL), GetTickCount()%1000, (UIDPostfix++)%100);

#else

sprintf(oString, "%s.%u.%u", UIDPrefix, (unsigned int)time(NULL), (UIDPostfix++)%10000);

#endif

I.e., it combines the prefix with a time and a counter.
