It's also included in the ifodump that comes with libdvdread.

Note that there are only TMAPT entries for sequential pgcs in the
Title domain.  Nothing for any of the menu domains, nor for random or
shuffle titles.  There will be TMAPs for pgc that are part of multi
pgc titles but they will generaly not have any time entries in them.

The time resolution is specified in the header and will vary between
DVD and/or titels.  It's ofthen 1 or 4 seconds, and generaly is more
corse for longer titles, i.e. a short 2 minute title will have 1
second resolution and the main movie that is 2h will have 4 second
resolution.
There might well be long PGC that just plain don't have any entries
in the TMAP, Magic Knight Rayearth Daybreak is one such DVD.
