<p>The length of time that you want a zonal shift to be active, which ARC converts to an expiry time (expiration time). Zonal shifts are temporary. You can set a zonal shift to be active initially for up to three days (72 hours).</p> <p>If you want to still keep traffic away from an Availability Zone, you can update the zonal shift and set a new expiration. You can also cancel a zonal shift, before it expires, for example, if you're ready to restore traffic to the Availability Zone.</p> <p>To set a length of time for a zonal shift to be active, specify a whole number, and then one of the following, with no space:</p> <ul> <li> <p> <b>A lowercase letter m:</b> To specify that the value is in minutes.</p> </li> <li> <p> <b>A lowercase letter h:</b> To specify that the value is in hours.</p> </li> </ul> <p>For example: <code>20h</code> means the zonal shift expires in 20 hours. <code>120m</code> means the zonal shift expires in 120 minutes (2 hours).</p>
