2) It is bad form to post here and not point out that you have already
asked elsewhere [1]. It looks like you already received a quality answer
there. Failing to link to previous threads is almost as impolite as
cross-posting to multiple mailing lists... read the Posting Guide for more
on mailing list etiquette.

dt2: start and end are 10 minute interval blocks spanning 2013-4-1 00:00:00
to 2013-04-04
I want to add the column 3 of dt1 to map as long as the start and end time
are within the 10 minute blocks and keep appending the columns
ideally the output should be
4/1/2013 0:00
4/1/2013 0:10
0.05 0
4/1/2013 0:10
4/1/2013 0:20

I tried
setkey(dums,start,end)
setkey(map,start,end)
foverlaps(map,dums,type="within",nomatch=0L)
I keep getting the error
Error in foverlaps(map, dums, type = "within", nomatch = 0L) :
All entries in column start should be <= corresponding entries in column
end in data.table 'y'
