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. The 'valid sources' command is used to get a list of interfaces which the clock is matching the requirements. The response contains a space separated list of interfaces, or "None" when not a single clock is matching all the requirements. Test plan: valid sources command PASS: Verify that a space separated list of interface is returned when one or more clocks match the requirements. PASS: Verify that the string "None" is returned when not a single clock match the requirements. Now the GM time traceable check is enabled by default as it is an important check for both T-GM and T-BC scenarios. The GM time traceable check is controlled in configuration by using the ha_gm_timeTraceable setting, and it can be disabled using the value 0 (ha_gm_timeTraceable 0). Test plan: default value PASS Verify the check is performed by default. PASS Verify the user can disable the check by configuration. Bonus: Fixed the behavior when none clock is matching the requirements and the active clock source is disabled using the 'disable source <interface>' command. The interface is must be disabled and a new clock source is selected. Test plan: none clock is matching the requirements PASS: Verify that the active source can be disabled and a new one is selected. PASS: Verify that an attempt to disable the last active interface fails and an appopriated message is given as response. PASS: Verify that the interface with higher priority is selected after re-enabling it. PASS: Verify the active clock source doesn't change if another interface is disabled. PASS: Verify the active clock source doesn't change if another interface is re-enabled.
