On 16 January 2020, the International Organization of Securities Commissions (IOSCO) published a report recommending that trading venues and their participants synchronise the clocks they use for timestamping a reportable event with coordinated universal time (UTC).

UTC is computed by taking the weighted average of more than 300 atomic clocks located in more than 80 timing laboratories around the world, including many of the IOSCO member jurisdictions. Although UTC itself is a paper timescale that is calculated and published after collating all the data from the timing laboratories, these laboratories each maintain real-time versions of UTC that are made readily available in their respective jurisdictions.
