When submitting mail by using sendmail as a mail submission program,
sendmail copies all messages to /var/spool/clientmqueue first. sendmail is
a setgid smmsp program and thus gives the any user the permission to do so
(/var/spool/clientmqueue belongs to user and group smmsp).

Later, another sendmail process, the sendmail localhost-only (FreeBSD
default config) mail transfer agent (MTA) copies the messages from
/var/spool/clientmqueue to /var/spool/mqueue and sends them to their
destination.

When files accumulate in /var/spool/clientmqueue, you probably don't run
the sendmail localhost MTA, and thus the mails don't get send.

# checkout a specified date/time version of project code in the UTC (Coordinated Universal Time). This command was worked for me.
# cvs checkout -D "2009-05-04 14:48:00 UTC" modulename

# The following format is not yet correct executed in my environment yet, but it was suggested by the net
cvs checkout -D "2009-05-04 14:48:00 +0800" modulename >> "+0800" means that the CVS UTC time will minus the "0800" and the real checkout time (UTC/GMT time) will be "2009-05-04 06:48:00"
or cvs update -D "2009-05-04 14:48:00 +0800" modulename

Note:
Greenwich Mean Time (GMT) can be considered equivalent to UTC time
