lead times

/L EH1 D T AY0 M Z/
noun
  1. 1

    The amount of time between the initiation of some process and its completion, e.g. the time required to manufacture or procure a product; the time required before something can be provided or delivered.

    It's an excellent device, but it has a 10-week lead time, so be sure to order it in advance.
