FIELD: watches and other time measuring instruments.
SUBSTANCE: invention relates to clock. Time device comprises a body, a dial, a clock mechanism and additionally comprises a Mars time equation indicating mechanism by which the deviation of the true solar time from the average solar time on Mars is displayed. Disclosed engineering solution significantly shortens the time for determining the difference between the average and true solar time on Mars, eliminating the need to calculate the difference.
EFFECT: creation of a time device with the indication of the time equation on Mars.
