Why 'W'Format?

Also, consider FormatWithSeconds instead of FormatWithSecondPrecision. Just my
opinion though, so feel free to ignore or let Stan decide.

What about sub-second precision? Should we consider that?

I vote for "WithSeconds", as the other one is "WithMinutes" basically though it
is not mentioned in the function name.

[chengx, 2016/12/20 00:51:12]

Done.
