Subject: [PATCH 51/56] Time traceable flag
|
|
|
|
A new time traceable flag was added to pmc agent to store the current
|
|
time traceable status.
|
|
|
|
This flag replaces the utc_offset_traceable flag in the HA clock
|
|
selection algorithm and status command.
|
|
|
|
Test plan: HA clock selection algorithm
|
|
PASS: Verify the clock source which time isn't traceable is discarded
|
|
by the algorithm if ha_gm_timeTraceable is enabled.
|
|
PASS: Verify the clock source which time is traceable isn't discarded
|
|
by the algorithm if ha_gm_timeTraceable is enabled.
|
|
|
|
Regression: status command
|
|
PASS: Verify the response of status command shows the correct GM time
|
|
traceable.
