[Samba] Strange problem - print_job_start: job start denied by time check

[Jules]

Hi,

Having a very odd problem with a printer that I've had up and running 
for over a year now with no previous issues.  There have been no 
software or hardware updates recently that should have affected it.  The 
printer is managed via CUPS and its details are loaded from the CUPS 
printcap.  At some point late on the afternoon of the 11th, samba 
started rejecting print jobs sent to it. Turning up logging details 
showed the following for a typical request:

[2011/01/12 01:29:19,  4] printing/nt_printing.c:print_access_check(5832)
   access check was SUCCESS
[2011/01/12 01:29:19,  3] printing/printing.c:print_job_start(2381)
   print_job_start: job start denied by time check
[2011/01/12 01:29:19,  3] smbd/error.c:error_packet_set(61)
   error packet at smbd/error.c(137) cmd=45 (SMBopenX) 
NT_STATUS_ACCESS_DENIED

This has happened quite a few times.  Since the problem started, I have 
been able to print successfully on one occasion.  This was a job that 
was sent to the printer at exactly 0100 GMT.  All other requests are 
denied with the time check message.

I have not configured any time restrictions on my printer, and accessing 
it via 'lpr' works fine.

smb.conf is reproduced below, with comments removed for brevity.  Samba 
version is 3.2.5 (debian package 3.2.5-4lenny13).
