Clock apparatus adapted to summer time, monitoring camera apparatus having the same, and clock apparatus time setting method

摘要

A timepiece comprises a standard time clock for counting standard time and means for calculating daylight saving time by adding a predetermined time correction value to the standard time when judging that the standard time is within the period of daylight saving time. When a time input for setting the timepiece is after a daylight saving time starting time as expressed in the standard time and before a daylight saving time starting time as expressed in daylight saving time, the timepiece corrects the input time by adding the time correction value thereto and sets the corrected time as daylight saving time for the standard time clock. A monitoring camera device comprises the timepiece. Time data output from the timepiece when an image is captured is added as image capturing time data to image data obtained by capturing the image.
