I think that: when the esp8266 is in deep sleep mode, the internal time is managed by a counter. The idea would be to compare the incremental value of the counter with an incremental real-time value before sleeping the esp8266. With these values, the counter and the real, would get a factor that would allow me to correct the time

just determine your factor and apply it to the deep sleep argument (µs)

any idea to get the factor without accessing the registers?

#70783 get micros(), do your reference stuff, get micros() again,
do some hocus-pocus, adjust the argument to the deep_sleep()

I don't know if it is only me, but I have no idea what registers you actually want to access ...
