FYI, the archives are 1/2 hour block clips and the times in the archives are UTC, not local time. So assuming you are looking for 10:00am-11:30am local you need to grab three clips: 1600z-1630z, 1630z-1700z , and 1700-1730z. Salt Lake City is UTC-6 or add six hours to your local time to get UTC time. After daylight savings time ends in November it will be UTC-7.
