We would need to know the OS and how the file system was mounted. As one example: Sun's mount_ufs man page documents the noatime option:
Quote:
By default, the file system is mounted with normal access time (atime recording. If noatime is specified, the file system will ignore access time updates on files, except when they coincide with updates to the ctime or mtime. See stat(2). This option reduces disk activity on file systems where access times are unimportant (for example, a Usenet news spool). noatime turns off access time recording regardless of dfratime or nodfratime. The POSIX standard requires that access times be marked on files. -noatime ignores them unless the file is also modified.
Another example: the source files might be on cd-rom.

PAM_TIME(8)							 Linux-PAM Manual						       PAM_TIME(8)

NAME
pam_time - PAM module for time control access SYNOPSIS
pam_time.so [debug] [noaudit] DESCRIPTION
The pam_time PAM module does not authenticate the user, but instead it restricts access to a system and or specific applications at various times of the day and on specific days or over various terminal lines. This module can be configured to deny access to (individual) users based on their name, the time of day, the day of week, the service they are applying for and their terminal from which they are making their request. By default rules for time/port access are taken from config file /etc/security/time.conf. If Linux PAM is compiled with audit support the module will report when it denies access. OPTIONS
debug Some debug information is printed with syslog(3). noaudit Do not report logins at disallowed time to the audit subsystem. MODULE TYPES PROVIDED
Only the account type is provided. RETURN VALUES
PAM_SUCCESS Access was granted. PAM_ABORT Not all relevant data could be gotten. PAM_BUF_ERR Memory buffer error. PAM_PERM_DENIED Access was not granted. PAM_USER_UNKNOWN The user is not known to the system. FILES
/etc/security/time.conf Default configuration file EXAMPLES
#%PAM-1.0 # # apply pam_time accounting to login requests # login account required pam_time.so SEE ALSO
