I want a footer (or header) to (1) increment the page number on each page after page 1, and (2) set up the date to always show current date.
Thanks.
Just Insert → Fields->the adequate variable.
(1) The page number is simply accessed with Insert → Fields → Page Number
(2) Current date is a bit different. If you choose Date (or Time), you get the dtae/time at which you inserted the field and the value is frozen. This is fine for log or other journal. In your case, to get an updatable field, choose Insert → Fields → Other.... In the dialog, select Type Time and Select Time (not Time(fixed)).
Whenever you need your date/time field changed to reflect current value, Tools → Update → Fields or F9 (or Tools → Update → All which will also update ToC, indexes and all other references).
