Question

Submission Date: 01 April 2026

For trading venues subject to the obligations in Article 12 (1) of Commission Delegated Regulation (EU) 2025/1155, which requires business clocks capable of achieving a granularity of 0.1 microseconds, would the dissemination of timestamps at this level of granularity in their existing market data feeds be considered compliant with the requirements in Articles 5 and 6 of Delegated Regulation (EU) 2025/1155 to provide timestamps to the CTPs with a less granular precision of six decimal places?


ESMA Answer

Answer Date: 01-04-2026

The RTS 2025/1155 specifies that the timestamp fields to be transmitted to the CTP must follow the ISO 8601 date‑time format with six decimal places (i.e. ss.dddddd) representing fractions of a second in microseconds, as set out in Table 1 of Annex III, where timestamps must be provided in the format YYYY‑MM‑DDThh:mm:ss.ddddddZ. ESMA confirms that a data contributor will be considered compliant with the timestamp requirements of Articles 5 and 6 of Commission Delegated Regulation (EU) 2025/1155 if it transmits timestamps with at least six decimal (microsecond) digits and follows the ISO 8601 format.
