# The rtcsync directive enables a mode where the system time is periodically
# copied to the RTC and chronyd does not try to track its drift. This directive
# cannot be used with the rtcfile directive. On Linux, the RTC copy is performed
# by the kernel every 11 minutes.

# This directive specifies the maximum amount of memory that chronyd is allowed
