SD Renter Sandicor does own the MLS but SDAR monitors and enforces the rules. When you take a listing you (the agent can edit the listing at any time. Recall your broker owns the listing and can do the same)
You cannot simply change the market time ad hoc. When you first enter the listing information the user interface is a template. Most all of the entries are pull down tabs. Some of them you can type in fields such as in the remarks or supplements. Anyways one of the fields you fill in is the expiration date.
Now once your listing goes active the market time will never reset to zero until the listing expires. Once the listing expires the listing goes from active to expired status. At this point only the broker may move it back to active status, AND the market time will not go back to zero.
HOWEVER, if the listing agreement has been renewed or a new one is put in place, the agent may submit a new listing on the MLS and that WILL have a market time of zero days.
Alternately the listing may be moved to the cancelled status. This means that either the broker or the seller cancelled thier listing agreement. Again, the listing will now move from active to cancelled status. Only the broker may move it back to active at this point if the two parties reconciled and market time would resume and NOT revert to zero. However once a new listing agreement is signed whether it is with the same broker or a different brokerage, the listing would be entered as a new listing on the MLS and market time would go to zero.
