Look at carefully Steve Kostecke's message where he said: -------------------------------- step == reset the clock to the correct time in _one_ instantaneous step. A stepped clock can "move backwards".
slew == adjust the clock by speeding it up or slowing it down. A slewed clock never "moves backwards" -------------------------------- you can see slewed clock never moves backward, it can decelerate or accelerate clock by 0.5 ms/sec, but not set time backward of several minutes ! ----- Original Message ----- From: Hal Murray Newsgroups: comp.protocols.time.ntp To: [email protected] Sent: Thursday, May 03, 2007 10:26 AM Subject: Re: [ntp:questions] stepping and slewing >Now I understand that stepping set clock immediately to correct time >(both forward and backward) while slewing permit to adjust gradually >time at max 0.5 ms /sec rate (ONLY forward). is'tt OK ? Slewing can go in either direction. To advance, the clock advances by 1.0005 seconds per real second. To backup, it advances by 0.9995 seconds per second. -- These are my opinions, not necessarily my employer's.
