Summary and statistics of the results of the questionnaire concerning the future of UTC.
The Questionnaire is given as an appendix
Since multiple responses were very often given, percentages represented on the pie take into account the fact that users are implied in different fields of activities .
3 - Are you satisfied by the current UTC determination method with leap second adjustements?
3-1 If YES, is the present forecast time (6 months in advance) of the occurence of a leap second sufficient? If not would you suggest another time delay? 1 year or more?
3-2 If NO, Why ?
4 - Do you think it would be better to change the determination method of UTC?
4-1 If YES, which alternative solution would you favour?
4-2 If NO for 4, why?
5 - Other comments regarding determination or operation of UTC?
6 - This question addresses to Bulletin D users (DUT1 with .1s accuracy). Is the present Bulletin D convenient ?
If NO, why?
If NO, would you prefer a more frequent and refined estimation? With which accuracy?
