The 44th SMIIC MC Training within the SMIIC MC Work Plan 2024 – 2026 V3 was the The Training on Time scale difference. Local clock vs. UTC(k) measurement uncertainty calculation held on the 12 September 2026 virtually, technically hosted by SMIIC General Secretariat. 14 experts participated in the training.
The training was hosted by NMI: Uzbek National Metrology Institue (UZNIM)
General Description: The training provides general information about the time scale difference measurement and its uncertainty calculation.
Objective, expected outcome: This training course aims to:
- Give information on the time scale difference measurement;
- Training on evaluation and calculation of measurement uncertainty.
Who should attend: The responsible staff for Time and frequency labs should attend the training.
