According the samba documentation:

sambaPwdLastSet: The integer time in seconds since 1970 when the 
sambaLMPassword and sambaNTPassword attributes were last set.

sambaPwdCanChange: Specifies the time (UNIX time format) after which the 
user is allowed to change his password. If this attribute is not set, 
the user will be free to change his password whenever he wants.

sambaPwdMustChange: Specifies the time (UNIX time format) when the user 
is forced to change his password. If this value is set to 0, the user 
will have to change his password at first login. If this attribute is 
not set, then the password will never expire.

"UNIX time format" (1) means exactly that time measured in seconds since 
1970, and your results appears to be coherent with time measured in seconds.

sambaPwdCanChange: 1183795200
sambaPwdLastSet: 1167638400

Your sambaPwdCanChange is 7 days (measured in seconds) beyond 
sambaPwdLastSet (thats is exactly the same result that pdbedit is showing).

Passwords can be forced to change using smbldap-tools "smbldap-usermod 
-B 1 user" too. And as the docs say, users are forced to change their 
passwords when sambaPwdMustChange is set to 0.

I don't know how your system used to be, but the docs says how it should
