Since GSW SSH2/Telnet was developed for Windows and is integrated with Windows security, you can utilize available features.
For example, the command line utility Net User can be used to limit logon times.
The net user command syntax is:
net user [username [password | *] [options]] [/domain]
username {password | *} /add [options] [/domain]
username [/delete] [/domain]
One of the options for net user command is /times:{times | all} Is the logon hours. The times option is expressed as day[-day][,day[-day]],time[-time][,time [-time]], and is limited to 1-hour increments. Days can be spelled out or abbreviated. Hours can be 12-hour or 24-hour notation. For 12-hour notation, use am, pm, a.m., or p.m. The all option specifies that a user can always log on, and a blank value specifies that a user can never log on. Separate day and time entries with a comma, and separate multiple day and time entries with a semicolon.
Please type the command net help user at a command prompt to obtain all the information of the Net User command and options..
