Why doesn't BIPM want TAI to be used for timestamps?
- sla29970 14y agoRead between the lines of http://www.bipm.org/cc/CCTF/Allowed/18/CCTF_09-27_note_on_UTC-ITU-R.pdf http://www.bipm.org/cc/CCTF/Allowed/18/CCTF_09-27_note_on_UT... about what systems of time distribution already exist and which of those are approved for use by national and international agencies.
- CamperBob2 14y agoTAI is calculated in retrospect, as I understand it, based on the weighted contributions of the atomic timescales maintained by all of the participating countries. As a result, if you store a TAI timestamp in hopes of using it as an absolute time reference point, you will have to go back and update it when BIPM releases the next 'Circular T' bulletin (http://www.bipm.org/jsp/en/TimeFtp.jsp?TypePub=scale http://www.bipm.org/jsp/en/TimeFtp.jsp?TypePub=scale).
