This How-To will explain the proper process for offsetting timing data in the event your timezone is incorrect.

Important Note: If your timezone is wrong and you have already started the race (data has already been collected), you should NEVER change the timezone. This will make things harder to fix. If it is prior to the race starting, you can correct the timezone, and you will not need the rest of this article.

Start by pausing your system connection under Timing > Chip Timing; select the yellow pause button on the far right.

Delete the wrong data. Navigate to Participants > Delete Data > Delete Timing Raw Data. Select "Show Raw Data Filters," which will open more filter options. Enter the device ID (full ID including letter prefix and dash) you wish to delete the raw data for (the one with the wrong times), then press Delete X Raw Data Entries.

Apply the offset and import reads again. Here we can see the time before the offset is applied. From Timing > Chip Timing > Chip Timing, select the details button for the system connection. This is the grey button to the far right.

This will open the details window where you can specify an offset. The offset will depend on how the time is off. If the clock on the system is ahead of the current time, apply a negative offset. If the clock is behind the current time, apply a positive offset. The example below applies a negative 1-hour offset.

With the offset applied, press the yellow play button to resume the connection, then press the blue rewind button to load all the passings again with the offset applied. You will notice that the time is now showing 1 hour less.
