Allows to synchronize with a clock ahead or late by a constant time
Anki's synchronization requires that your time is synchronized with ankiweb's time. The error should be less than 5 minutes. If, for some reason, your computer is late or ahead by a fixed time, this add-on allows you to synchronize.
By default, this add-on is configured to work for computers five minutes ahead (because this was requested in https://www.reddit.com/r/Anki/comments/7jooar/is_it_possible_to_use_ankiankidroid_with_a_clock/ ).
