I suspect that you might be referring to a 150-day order. These are issued by the court to try to "move the case along" and remind the parties of the deadlines in the case. You will want to review the order carefully to make sure that you comply with all deadlines, otherwise you will run the risk of having a ruling against you.
The 150-day order will set forth a date by which a motion to set must be filed (or an arbitration award filed) in order to keep the case on the active calendar with the court. There will then be another date on which the matter will actually be dismissed if a motion to set or arbitration award hasn't been filed. Obviously, that date is EXTREMELY important.
There is also an order issued by the courts when 120 days have passed since an arbitrator was appointed to handle a court-mandated arbitration. This order is a reminder to the parties and the arbitrator to get a date set for the arbitration and to notify the court of that date immediately.
