There is no 'default' way. The reason for that is that protocol
buffers are platform independent, and there is no real agreeable way
to represent timestamps on all platforms; there are seconds,
milliseconds and microseconds since 1970 around; yet other system
represent times in even higher resolution since a different epoch
start.

Also, having protocol buffers handle timestamps might actually be too
generic; suppose you want to be sure to be interpretable in a
sufficient high resolution and protocol buffers choose to encode
microseconds since, say, 1970. Then this will encode in huge numbers (
= more wire bytes) - but OTOH, this is not really what is needed in
all contexts.

So - best is to have the application choose the time resolution that
makes sense depending on the application and deal with it in an
application dependent manner (e.g. I store seconds, milliseconds or
microseconds since 1970 GMT or Julian dates in protocol buffers to
transfer times in different contexts).
