[Cin] Repair some TODO from latex source

[Andrea paz]

Also, I think the example of "around" was correct before your change
but I am too lazy to test it out so left that change in.  I.e. I think
"around" goes + and -.  Example line is:
>>
>> Or      &Time&  Around&2018/08/02 06:00:00 + 02:00:00  & files at 6AM to 8 AM

Go ahead and put the value "4AM" back; it is likely that I did not
understand the example....
