man 5 shadow

 shadow  contains the encrypted password information for user’s accounts
 and optional the password aging information.  Included is
 
       Login name
 
       Encrypted password
 
       Days since Jan 1, 1970 that password was last changed
 
       Days before password may be changed

       Days after which password must be changed
 
       Days before password is to expire that user is warned
 
       Days after password expires that account is disabled
 
       Days since Jan 1, 1970 that account is disabled

       A reserved field

======
To convert easily from seconds to some date that I understand I use the
"date" command.  For example to see what date 1056441755 seconds is...

   date -d "jan 1, 1970 GMT +1056441755 second"
