[R] Zoo series to a date time stamp that is regular

[stephen sefick]

NOTE: I will provide data if necessary, but I didn't want clutter
everyones mailbox

All:
I have a time series with level and temperature data for 11 sites for
each of three bases.  I will have to do this more than once is what I
am saying here.  OK,  The time series are zoo objects with index
values in chron format.  The problem is that the date and times should
be at even 15 min intervals, but because of operator error (me) they
are on 15 min intervals for some of the data and on 15+1 min intervals
for some and 15+1.56 for some of the same site.  I would like to
create a regular 15min time series from this and need to know if I can
just create an empty time series with the entire date time I would
like and then aggregate.  I am not sure how merge or aggregate would
act in this particular situation.  I want to "snap" readings to the
nearest 15min interval.
kindest regards,

Let's not spend our time and resources thinking about things that are
so little or so large that all they really do for us is puff us up and
make us feel like gods.  We are mammals, and have not exhausted the
annoying little problems of being mammals.
