What does the end of daylight saving mean for regulatory reporting?

What does the end of daylight saving mean for regulatory reporting?

On October 30, usually in the early hours of the morning, clocks across the UK and the majority of mainland Europe fall back an hour.  Since Europe spans several time zones, the switch occurs at different local times. 

Whilst you may need to adjust the clocks at home and hunt for the instruction book to change the one on the oven, please remember that the time fields for UK & EU MiFIR trade and transaction reporting and EMIR trade reporting should be populated in Coordinated Universal Time (UTC).

The regulators are not likely to be sympathetic if you make errors following these time transitions and the UK’s FCA has warned firms of such mistakes in Market Watch 59:

“The time when the transaction was executed should be reported in Coordinated Universal Time (UTC). We continue to see errors in transaction reports when UK clocks transition to and from British Summer Time, as well as errors driven by inaccurate clock synchronisation. Firms should have arrangements in place to ensure consistent and accurate reporting of trading date and time.”

The CSSSF in Luxembourg has also commented as to the importance of this field:

“In the context of data quality tests performed on transaction reports, the CSSF identified that in several transaction reports the time indicated in field 28 “Trading date time” was the local time instead of UTC. Investment Firms have been informed that, within the framework of the transaction reporting obligation, dates and times shall always be reported in UTC.”
