Hello Gil,

interesting flow.

You get a different result if you:

1.   LOGON FUBAR  --> IKJ564201I message and blank fields.
2.   Overwrite the bad "*Userid    ===> FUBAR" with a valid userid and PRESS 
ENTER
3.   Rest of fields are now loaded with values. (proof of valid userid).
4.   Modify fields as necessary.  e.g. type TIME in COMMAND field
5.   Lastly enter your password.

In this flow the TIME command will be processed as expected.
