I find this confusing as the icons in the System Tray, (where the clock, volume icon, and other icons sit), should always be displayed.
On the taskbar, the following should always show;
Far left - The Start menu button.
Far right - The System Tray, (sometimes called the notification area).
In the middle - The taskbar icons for any running programs, and they will be squashed up as more programs are running.
There is no easy method, ie no settings available to a normal user such as you and I, to remove the clock, although other icons in the System Tray can be hidden. To do that, right click any empty part of the task bar and select Properties, then in the window that appears, click the Customize button. This allows you to choose which icons to show/hide and when.
But that doesn't seem to be your problem.
I must admit that your first post was a bit confusing where you said ''My husbands side of the computer''. What do you mean by ''his side''? Do you have two monitors?
Also, when you say you have enlarged his letters et al, how did you do this, and is there a reason why you did?
How many icons other than the clock are displayed in the System Tray at the moment?
What size monitor do you have, and what is the screen resolution in Display Properties > Settings?
What happens if you increase the screen resolution by a notch or two. Does the clock display re-appear?
