How do I figure out my Universal Time Coordinated (UTC) difference?

• See the table below to determine the Time Difference (UTC) setting for your time zone. The table below covers Standard and Daylight Saving Time (DST) for North America.

  If you are in a region that observes daylight savings time (DST), please turn on DST, set the DST detailed settings, and set the UTC time difference on the projector to the highlighted value in the table for your time zone.

  You can also search for your UTC time difference online using your zip code.
