I don't pretend it's my idea, I just coded it. My boss proposed the 
feature as such :-)

Sure, will do in the next version.

Because both receivelog.c and pg_basebackup.c need it now. I thought I 
could move localTimestampDifference() and 
localTimestampDifferenceExceeds() as well for the sake of consistency 
(these are actually utilities too) but I didn't get convinced enough 
that the feature alone justifies such a change.

As mentioned in 
http://www.postgresql.org/message-id/20130731173624.GX14652@eldon.alvh.no-ip.org 
these functions ideally shouldn't have separate implementation at all. 
However the problem is that pg_basebackup is not linked to the backend.

You're right about sys/time.h, it's included via via streamutil.h. I'll 
fix that too.

Whenever you have time. Thanks!
