Our PAR-100 automatically takes care of clock altering for summer/winter time changes. The dates and times are pre-programmed into the control unit, and your clock will pause for eleven hours (effectively forward by one hour) in the spring and one hour (back) in the autumn.
If your clock has night silencing, the spring time change can be programmed for 23 hours to maintain chiming continuity.
Quartz Time Control (Standard) Timekeeping is governed by an on-board clock, accurate to within ±2 seconds/year at a temperature range of between -40 and +85 Celsius (military specification), in the PAR-C-100 control unit. GPS Time Control (Optional)
