linux 中/etc/shadow 文件中有个account expiration date 字段

C/C++ code

The date of expiration of the account, expressed as the number of           days since Jan 1, 1970.           Note that an account expiration differs from a password expiration.           In case of an acount expiration, the user shall not be allowed to           login. In case of a password expiration, the user is not allowed to           login using her password.           An empty field means that the account will never expire.           The value 0 should not be used as it is interpreted as either an           account with no expiration, or as an expiration on Jan 1, 1970.
