All about time is about the use of time. So what is your use-case?
Time is either some "point in time" (like a date) or "duration". Your use-case is not the first one because a "point in time" is bound to a location (it 10am in Paris,FR ... not 10am). As a duration, it's only really usable as a duration inside the same 24h period... and for this everybody already has the second. The replacement of a base 86400 by a base 100000 does not really seem to me as a game-changer (not for computer and not really for humans either) so I don't think that anybody will take the time to use it somewhere.
I think that if you want to work on "time", you could help with 2 "hard" problems :
* calendars : the main PITA is more that months dont have the same length in days (not even for the same month in case of february) and neither the same number of "workable" days. Some calendars try to help by using 13 * 28 days month (each month=7 days weeks... so same count of workable days). That kind of calendar is used in finance I think but not really sure
* outside earth (meaning lunar, martian... really Universal) time duration & calendar : for now, our calendar and time mesurement is based on earth rotation on itself (night/day succession) and around the sun (seasons succession). These notions dont have a lot of sense on earth or on mars... or outside our solar system... So: should we use some kind of percentage of total revolution or that kind of thing ?
I think that tackling that kind of problem could be more a game changer that building a system to replace 1 second by a pulse with a duration of 0.864 second. YMMV
