CT question

[KR4DL@aol.com (KR4DL@aol.com)]

I am using CT ver. 9; during 160 phone contest I worked a local and forgot to
log him.  Later (the next day) I discovered my error and asked him when we
worked.  I entered him in the log and changed the time and date, figuring CT
would move the QSO to the right spot.  It didn't.  Now I have a QSO from Feb.
24th stuck in the middle of Feb. 25th.
A: Does it matter?
B: Can I correct it?
C: If so, how?
Thanks in advance for any help.  73,
Steve  KR4DL
