GET the corect date and timezone of the client in Dynamics 365 for Finance and Operations

Many a time we get a requirement to fetch exact data and time from a user , in that case we can use system inbuilt function from DateTimeUtility

Below is such a scenario we faced from checking the date must not be lesser than today. This code fit in the best way.

 public boolean validateField(FieldId _fieldIdToCheck)

    {

        boolean ret;

    

        ret = super(_fieldIdToCheck);

        switch(_fieldIdToCheck)

        {

            case fieldNum(ConVMSVehicleTablePhase2, AcquiredDate):

                Timezone clientTimeZone = DateTimeUtil::getClientMachineTimeZone();

                TransDate today = DateTimeUtil::getSystemDate(clientTimeZone);

                if(this.AcquiredDate < today)

                {   

                    ret = checkFailed("@ConVMS:AcqDateMustBeTodayOrLater");

                }

        }

    

        return ret;

    }
