Conversion to daylight saving time 2018
On gas day 27 October 2017 there will be a switch from summer time to winter time. This means that this gas day will have 25 hours. To avoid any problems please be aware of the following:
We expect nominations according the EDIGAS protocol. This means that a nomination for this gas day (October 27th) consists of 25 hours in which, translated to UTC, the nomination for that day begins at 04:00 UTC (6.00 LET) and ends at 05:00 UTC (also 6.00 LET). When using ENOM with appropriate settings, this feature is facilitated when nominating for this gas day. When not using ENOM, please make sure that Edigas messages will have this timeframe.
Whenever possible, avoid sending in nominations in the period between 01:00 LET and 04:00 LET. Due to possible technical limitations, incoming nominations may be handled different from the normal process and therefore may introduce extra risks.
