i m able to get a probable solution on this website which shows how to solve the problem (tracefile events not sorted by time) http://sokoyo.csit.tw/~blog/2008-07-10/155 but i dont know how to convert %.9f to time format characters bearing in mind that the TR files produces time in the format 0.504153598 for example. thanks
