To truncate to the hour …

DATEADD(
  {time},
  -1 * MINUTE({time}),
  "minutes"
)

If your time has seconds, you may also needs to do the same pattern to subtract seconds.

Note that this is different from rounding to the nearest hour. 10:59 would turn into 10:00, not 11:00. If you want to round to the nearest hour, that is a different formula.

IF(
  MINUTE({time}) < 30,
  DATEADD(
    {time},
    -1 * MINUTE({time}),
    "minutes"
  ),
  DATEADD(
    {time},
    60 - MINUTE({time}),
    "minutes"
  )
)

As for showing the time in Central time, you can use DATETIME_FORMAT() along with SET_TIMEZONE().

Worked. Absolutely part of the puzzle. Many Thank Yous.

I'm trying to do the exact same thing and it isn't working... Help? 

The total time is = Prep Time + (End Time - Start Time) 

 

I want to ROUNDUP the total time to the nearest quarter hour and was trying this formula to the nearest half hour and it doesn't work.
