This commit adds the support for "DateTimeLocalOffset" property under
"/redfish/v1/Managers/bmc/" Redfish URI.
And it also adds the support for "DateTime" & "DateTimeLocalOffset"
properties under "/redfish/v1/Systems/system/LogServices/<id>/" &
"/redfish/v1/Managers/bmc/LogServices/<id>/" Redfish URI's.
