ctime - Connect time and accounting info
Ctime displays information about your connect time. The current time, the time you logged in, and the previous login time are shown, along with the total number of hours used for your current session, the current month, and previous month, and the total hours spent online since your account was opened. It also tells you how many times you have logged in, as well as the total number of days that you can go without logging in before your account is automatically removed due to inactivity. Current and previous month’s access charges are also shown, if any.
If ctime is invoked from the ‘!’ command in login, the account statistics for the system will be shown, displaying amassed logins and hours since the system went online.
