The custom date range was already in server time (from LocalToServerTime), but the chart axis limit code added UtcOffsetMinutes again, shifting the X-axis by the server's UTC offset. With UTC-8 this caused an 8-hour shift (e.g. picking 8 AM-12 PM showed 12 AM-4 AM on the axis). Fixed in all 4 chart methods: blocking trend, deadlock trend, wait stats, and perfmon.
