A time counting assembly with a display for world time zones comprised of a power source, a second counter, a minute counter, an hour counter, and a time zone display for displaying a correct time over a faceplate. Stir the time zone adjustable ring with the hand to align a first landmark of a local time zone with a fixed point and then calibrate the time counting assembly in accordance with the local time, and then stir the time zone adjustable ring with the hand to align a second landmark of another locating time zone with the fixed point such that the inner gear ring moves the planetary idle gear set and the planetary base wheel to shift engagement of the engaging hooks in the ratchet holes, and the front hour wheel is rotated on the planetary base wheel with a planetary movement along the minute wheel set to cause rotation of a meshed hour wheel so as to turn a hour hand to the time in accordance with the time zone corresponding to the second landmark. The direct time zone adjustment design greatly reduces the thickness of the assembly so that the time counting assembly is usable in a watch or low-profile timer while maintaining world time zone display and adjustable functions, and providing a modularized design function for ultra-thin time recording device.
