Data processor with clocking for various world times

摘要

A data world times clocking includes a main clock for clocking a reference time and prestorage memory for prestoring names of cities in various time zones in the world and a time difference between the reference time and a standard time for each of the various cities. An input device permits an operator to specify a time difference and a name of a city other than the names of various cities prestored in the prestorage part. Upon such specification of the time difference, a readout device calculates a standard time based on the time difference and reads out the calculated standard time and one of the prestored names of cities which exist in the same time zone. Upon entry of the name of a city other than the names of various cities prestored in the prestorage means, the read-out name of a city is replaced with the name of a city entered through the input device. A display displays the replaced city name and the calculated standard time.
