All time requirements use Network Time Protocol; it communicates with a time server on the Internet by sending a request packet, then waits for a "good" return packet. If it is not a "good" packet; then process starts over --all of this takes more than microseconds, otherwise, date and time would be incorrect.
Advantage of NTP is there is no Real Time Clock required for time requirements! Earlier versions of the code use a DS3231 Real Time Clock. Using NTP allows adjusting the time automatically for Daylight Saving Time.
