A rather crucial error above kept this from working 
Code:
FUNCTION SIGN_IN_FocusButtonClick AS V ( )
if browse1:sign_in.value = "" then
browse1:sign_in.value = time("0h:0m AM",now())
else
dim vtime as Y
vtime = ctot(ui_get_short_time("Sign In Time",time("0h:0m AM",now() )))
browse1:sign_in.value = time("0h:0m AM",vtime)
end if
topparent.commit()
browse1:sign_in.refresh()
END FUNCTION
Since this subject has little info available and the other posts have no links anymore, thought I should update this. Also 'this.value' will not work, since this is not the same type of event that a _buttonclick or _titleclick event would require. You do not include 'this.Set_Viewport_row(row)' or use the same parameters in this function, and instead address the column field as above.
