13 - Compile phosphor-time-manager with default options:
20 - Compile phosphor-time-manager with some configurable options:
38 - /xyz/openbmc_project/time/bmc
43 set the time. For example on an authenticated session:
45 - To get BMC's time:
50       /xyz/openbmc_project/time/bmc xyz.openbmc_project.Time.EpochTime Elapsed
53   curl -b cjar -k https://${BMC_IP}/xyz/openbmc_project/time/bmc
56 - To set BMC's time:
61       /xyz/openbmc_project/time/bmc xyz.openbmc_project.Time.EpochTime \
67       https://${BMC_IP}/xyz/openbmc_project/time/bmc/attr/Elapsed

112       https://${BMC_IP}/xyz/openbmc_project/time/sync_method/attr/TimeSyncMethod
118 new beahvior that it checks the NTP services' status during setting time,
