I want to change the date timestamp for the log file but to do it within crontab
I've tried the following..

pam_timestamp_check
PAM_TIMESTAMP_CHECK(8) Linux-PAM Manual PAM_TIMESTAMP_CHECK(8)
NAME
pam_timestamp_check - Check to see if the default timestamp is valid
SYNOPSIS
pam_timestamp_check [-k] [-d] [target_user]
DESCRIPTION
With no arguments pam_timestamp_check will check to see if the default timestamp is valid, or optionally remove it.
OPTIONS
-k
Instead of checking the validity of a timestamp, remove it. This is analogous to sudo's -k option.
-d
Instead of returning validity using an exit status, loop indefinitely, polling regularly and printing the status on standard output.
target_user
By default pam_timestamp_check checks or removes timestamps generated by pam_timestamp when the user authenticates as herself. When the
user authenticates as a different user, the name of the timestamp file changes to accommodate this. target_user allows to specify this
user name.
RETURN VALUES
0
The timestamp is valid.
2
The binary is not setuid root.
3
Invalid invocation.
4
User is unknown.
5
Permissions error.
6
Invalid controlling tty.
7
Timestamp is not valid.
NOTES
Users can get confused when they are not always asked for passwords when running a given program. Some users reflexively begin typing
information before noticing that it is not being asked for.
EXAMPLES
auth sufficient pam_timestamp.so verbose
auth required pam_unix.so
session required pam_unix.so
session optional pam_timestamp.so
FILES
/var/run/sudo/...
timestamp files and directories
