I expect that like every RTC (real time clock) also the RTC of the soundtrap drifts: a good crystal (20 ppm) may drift up to 10 minutes per year if kept constant at 25 °C.

If the temperature changes the drift increases quadratically in temperature difference from 25 °C (0.04 ppm/°C^2 typical)

more details can be found in here and here
