A correct event displayed at the wrong assumed time is operationally useless. Calendar preparation should confirm the timezone, daylight-saving status, and the clock used by the trading chart.
Local time and UTC
A calendar may translate releases into device time while a broker chart uses UTC or another server timezone. Record both when testing or planning.
Daylight-saving transitions
Regions change clocks on different dates. The apparent relationship between London, New York, and a local timezone can shift during transition weeks.
Verify device settings
Automatic timezone settings and an accurate system clock help prevent errors. When traveling or using a virtual machine, confirm what timezone the interface actually detects.
Store event data consistently
For research, save a canonical UTC timestamp and convert only for display. This prevents duplicated or shifted records when daylight-saving rules change.
Preparation checklist
- Confirm displayed timezone
- Compare chart timezone
- Check daylight-saving changes
- Use UTC in research records
- Recheck on the event day
Frequently asked questions
Why did a release appear one hour later?
A daylight-saving change or mismatch between calendar and chart timezone is a common cause.
Which timezone is best for backtesting?
UTC is a useful canonical reference as long as all chart and event timestamps are converted consistently.
