The command syntax generally looks right to me, though (an aside) you are
allowed to put in certain metacharacters to make the date/time strings
more readable, e.g.

teqc -st 2009-01-23-21:29:08 -e 2009-01-23-23:36:31 57730230.09o > t0230.09o

What do you get if you execute the following?

teqc +mds 57730230.09o
