Using Sophis Risque 5.3.7 and equivalent Value version or less, negotiation date of the deals done by the trader are stored into database using the local time zone of the machine on which Sophis Risque is launched. Unfortunately, on multisites/multi countries architecture, the timezone is not stored into the database, raising an issue on the last requirements for compliance and regulatory checks. The goal of this post is to explain how to add the required timezone.
