Streets and Trips GPX problem with time

[routeconverter]

It turns out that Streets and Trips saves the time in Standard Time in the time zone. As a result I am in Eastern Daylight Time -4, the record says -5. While I know it should always show Zulu time, the fact is that it does NOT... so what now?

Maybe another workaround that creates GMT/Zulu time out of the read time if the creator is "Microsoft Streets & Trips"? (Like the speed Km/h vs. m/s workaround for Mobile Action)
