has anyone had this dash light come on before?

The other day, I noticed the air bag light came on and stays on. Also the clock now flashes. I dont know if these two conditions are related but as I say, they both occured the same time. I appreciate any suggestions.
Thanks

this happend to me the day after i purchased my XL7 there is a box under the front pasanger seat that controls the airbag for the pasanger side and also the radio. what they told me is a sensor was bad. its less than $200 to fix but it wasnt covered under my extended warenty.
