When I list out the file using ncdump, I see the times defined as:

        double timeObs(timeObs) ;
                timeObs:units = "seconds since 1970-01-01 00 UTC" ;

and the values:

 timeObs = 1159955951, 1159955952, 1159955953, 1159955954, 1159955955,
    1159955956, 1159955957, 1159955958, 1159955959, 1159955960, 1159955961,
    1159955962, 1159955963, 1159955964, 1159955965, 1159955966, 1159955967,
    1159955968, 1159955969, 1159955970, 1159955971, 1159955972, 1159955973,
    1159955974, 1159955975, 1159955976, 1159955977, 1159955978, 1159955979,
    1159955980, 1159955981, 1159955982, 1159955983, 1159955984, 1159955985,
    1159955986, 1159955987, 1159955988, 1159955989, 1159955990, 1159955991,
    1159955992, 1159955993, 1159955994, 1159955995, 1159955996, 1159955997,
.....

Since the units are in seconds and the values are integers, then the
resolution is 1 second, not .5 seconds.  When I load this into the
IDV, I get a time animation of every second and if I put a probe
into the display, I get a value at every second.   If I export the
probe to a CSV file, I also see data every second. 

So, I'm confused as to the problem.  Could you recreate the problem
on your end, then fill out the support form and include the
current state as a bundle?  Don't worry about the file paths, but
make sure you include the file that is causing problems if it is
not already one of those you sent.
