Red Hat Bugzilla – Bug 679034
ntpstat doesn't include root delay in maximum error estimate
Last modified: 2012-06-11 09:25:55 EDT
Description of problem:
The "time correct to within" value printed by ntpstat doesn't include root delay, only root dispersion, so the actual error might be larger than what is reported.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
2. ntpq -c 'rv 0'
3. compare rootdelay / 2 + rootdisp with the ntpstat's value
Technical note added. If any revisions are required, please edit the "Technical Notes" field
accordingly. All revisions will be proofread by the Engineering Content Services team.
The "ntpstat" command printed an incorrect maximum error estimate. This occurred because the "time correct to within" value did not include the root delay. With this update, the value includes the root delay and the displayed "time correct to within" value is correct.
