I have written a simple ULP program which takes BME280 I2C data and the sample time by querying the RTC registers and saves it into a buffer in RTC memory. After having collected 180 samples, it wakes up the ESP32 in order to copy these samples from RTC memory to SPIFFS. While copying the data I print all the sampled values and I see that sometimes the rtc timestamps skips a sample (the ULP program is scheduled to run every second, debug output is below, the drift happens at 17:52:38). I double checked all the time functions to record the data and to print the values and they seem to be correct (I attach them below). Has anybody experienced also this drift in its ULP code ? I strongly doubt that it's RTC drift since it happens only after 1:06 mins since last NTP synchronization.

* An overflow in the (ticks * cal) multiplication would cause time to
