I am using millis(). For timing purposes; with furnace elapse run times, is this adequate?

Tools and utilities exist to compile and run Arduino sketches on ESP8266s. What if instead we wanted to port those Arduino sketches to native ESP8266 code? Can we find mappings between the Arduino APIs and the corresponding ESP8266 APIs?

-- from Kolban's Book page 160:

Arduino: millis()

ESP8266: system_get_time() / 1000
