+        Whether to assume the system clock is unsynced. This applies to the ratelimit handling
+        code. If this is set to ``True``, the default, then the library uses the time to reset
+        a rate limit bucket given by Discord. If this is ``False`` then your system clock is
+        used to calculate how long to sleep for. If this is set to ``False`` it is recommended to
+        sync your system clock to Google's NTP server.
