Retrieving git log in YYYY-MM-DD format in local time zone

With git 2.7, use:

git log  --date=iso-local

git 2.7 (Q4 2015), which introduces -local as an instruction.

It means that, in addition of:

--date=(relative|local|default|iso|iso-strict|rfc|short|raw)

you will also have:

--date=(relative-local|default-local|iso-local|iso-strict-local|rfc-local|short-local|raw-local)

You now can ask for any date format using the local timezone.
