According to the U S Naval Observatory, the correct time of the Summer Solstice today will be 17:59 MDT.

The USNO lists astronomical solstice as June 20, 23:59UT http://aa.usno.navy.mil/data/docs/EarthSeasons.php - a minute before 6pm local time, for pagans out there who need to sacrafice a goat at the correct time. So you pagans still have a few minutes to get ready. If a goat isn't available, I understand a seagull is an acceptable local native alternative. The time of local solstice - the highest point that the Sun reaches in the local SLC horizon system during this calendar year as registered on local sundials - something not generally recognized by professional astronomers - was a few hours earlier at 1:30pm MDT. - Kurt
