Do you mean something like:

timezone: UTC -0400

[gianpaj]

For the summary yes.
Similarly there could be a --timezone setting that would print any times with that timezone.

For example if one log is UCT -4 and another UTC -5 and you say:

mloginfo mongod-countryA.log mongod-countryB.log --timezone 0100

then it would output any date by converting any time to that specified timezone

[rueckstiess]

Your second feature request "shift logfiles by timezone" is already implemented in mlogfilter.

--timezone [N [N ...]]
                        timezone adjustments: add N hours to corresponding log
                        file, single value for global adjustment.
