Timezone

Timezone

Control which timezone is used across the app. Access this page in Settings → Timezone.

Modes

Two modes:

• System — uses the browser's timezone
• Custom — select from a list of IANA timezones

Common Presets

US Eastern, US Central (Chicago/CME), US Mountain, US Pacific, London, Berlin/Frankfurt, Tokyo, Hong Kong, Sydney, and others.

Impact

The timezone controls how every UTC timestamp in the app is rendered: trade execution times, daily/weekly/monthly bucket boundaries, dashboard chart axes, journal entry dates, and the time-of-day filter. Underlying data stays in UTC, so switching timezone never alters a stored value, only its display.

Migration

Trade open and close dates (used to bucket trades into days, weeks, and months) are computed from the UTC timestamp at the moment a trade is created or imported. Changing your timezone afterwards does not re-bucket older trades. Run the migration to recompute those bucket dates against the new timezone — typically necessary when you relocate, when you fix an initially wrong setting, or after importing data from a broker in a different timezone. The job processes trades in batches and can be re-run; it never modifies the underlying execution timestamps.
