A issue about "Get Time Difference" in test_ipmi_sel_time.robot

[Julia-Delta]

When I test ipmi sel time items, I got value -1 about the difference between BMC time and SEL time.
I found that the parameter order seems wrong.
In line 134, line 285 and line 337, the diff time was get_sel_time minus bmc_time.
But bmc_time was the newest time, so the diff time maybe negative number.
I think that the condition need to modify and change "${difference}= Get Time Difference ${get_sel_time} ${bmc_time}" to "${difference}= Get Time Difference ${bmc_time} ${get_sel_time}"

yes, this requires code change.
In line 134, line 158, line 285 and line 337 these 4 lines the changes needs to be done.
