Availability Time Planning

Hello Experts,

I want to do Availability Time Planning for my channel.

But i am not able to understand i should give One-time or Daily in that.

Actully my requirement is like my channel should start on 17th March 2008 morning 6 o'clock and then it should follow the polling interval which is specified in the channel configuration. So it will be the daily or one time?

Can any one help me out in this please?

Regards,

Hetal
