PURPOSE:To provide a time display in which the expected arriving time at each check point, not different significantly from actual arriving time, is displayed even if the traveling speed is modified in the way after start of traveling. CONSTITUTION:The time display comprises a control CPU 1 and every time when arriving at each check point, a specific switch is depressed at a switch section 10 and the difference is determined between an expected arriving time at a check point (stored in RAM 9) and a current time received from a time/ date counting circuit 4. The expected arriving time to each check point is then modified depending on the difference thus determined before it is presented on a digital display section 8i. |
