[mkgmap-dev] access times?

Hello list, There's a street in the center of my town where access is forbidden on thursday and saturday. Now there seems no good way to enter such information in Openstreetmap (but that's a wholly different discussion). The reason I'm writing here is: do Garmin maps have a way to encode time-dependent access schemes? And, if yes, does mkgmap? (And if yes still, is there a way to use this information - as OSM is lacking it currently?) Best regards, Valentijn
