Function Documentation

void clock_close (  void   )

Called at shutdown time to cleanup local structures.

time_t clock_gmt2loc (  time_t  stamp  )

Given a GMT timestamp, convert it to a local stamp using our skew.

void clock_init (  void   )

Called at startup time to initialize local structures.

time_t clock_loc2gmt (  time_t  stamp  )

Given a local timestamp, use our skew to correct it to GMT.

void clock_update (  time_t  update, gint  precision, const host_addr_t  addr )

Update clock information, with given precision in seconds. The `ip' is used to avoid using the same source more than once per REUSE_DELAY seconds.
