This is the same reason why, on Terminal Server systems, caret blinking is typically disabled. This is generally not a great thing, since it basically means that the system is spending all of its CPU updating clocks. So once a second, a hundred stacks would get paged in so that a hundred taskbar clocks can repaint. Rather, each user that signs in has their own taskbar clock, that would need to update every second. On multi-users systems, like Terminal Server servers, it’s not one taskbar clock that would update once a second. But computers nowadays have lots more than 4MB of memory, so why not bring back the seconds?Īlthough it’s true that computers nowadays have a lot more than 4MB of memory, bringing back seconds is still not a great idea for performance. Originally, this was due to the performance impact on a 4MB system of having to keep in memory the code responsible for calculating the time and drawing it. The clock in the Windows taskbar does not display seconds.
