Just to give an actual set of steps to expand on the answer from Sam

  • Go to Utilities -> Terminal
  • If connected to Wifi, use ntpdate

    ntpdate time.apple.com

  • If not on wifi, use date command

    date 1201160419 # Sets date to 4:04PM Dec 1, 2019

  • Quit terminal and restart install procedure

  • The date command works [month][day][hour][min][year]. For [year] only use the last two digits, for example 2019 would be put in as 19. – Sam Dec 3 '19 at 18:35

I just set the date in terminal using the date command, and it is now letting me install macOS Sierra

  • Which is all good and stuff, but my external hdd connected isn't being recognized so I can't restore from backup – Sam Nov 15 '18 at 16:48

    I set the current date and it worked. Tried with dates which should correlate better to the release of the Sierra version in September of 2016 but that did not go through at all. – Gesias Nov 27 '18 at 10:23
