from the json response ,we can see :

"dstStartTime": "1:00u"
"dstEndTime": "1:00u"

 /// <summary>
        /// The local time when DST starts, hh:mm format
        /// </summary>
        [DataMember(Name = "dstEndTime", EmitDefaultValue = false)]
        public string DstEndTime
        {
            get
            {
                return DateTimeHelper.GetUTCString(EndTime);
            }
            set
            {
                EndTime = DateTimeHelper.GetDateTimeFromUTCString(value);
            }
        }

dstStartTime and dstEndTime value "1:00u" is not a valid DateTime .

This looks like a breaking change in the service as the documentation for these properties say the format is "(+/-)h:mm". I recommend reporting this issue at the Bing Maps Enterprise support team here: https://www.microsoft.com/en-us/maps/support
