Time Zone Information

The Day One apps store all dates in UTC. Newer versions of Day One also include the time zone where each journal entry was entered.

Entries without time zone information

Older versions of Day One did not record the current time zone in the journal entry. For these entries, dayone_export makes a guess based on the time zone in other entries.

If you would like to manually set the time zone in a journal entry which was recorded with an older version of Day One, insert the following section directly into the entry’s plist file:

<key>Time Zone</key>

This should be a key in the top-level dictionary. For more guidance on where to place it, look at an entry created by a current version of Day One.
