An economic calendar shows a release at 14:30. Is that London time, New York time, the server's time, or the user's local time? The answer depends on the settings of the website, and it can silently change.

Many traders have been caught by the mismatch during the weeks when the US and Europe are on different daylight saving schedules. A release that is always at 8:30 Eastern shows up at a different local time for a European viewer for two or three weeks each year.

The effect is the opposite of cautious. A trader thinks the release is an hour away, enters a position, and the news hits.

Another source of confusion is that some calendars display the time in the browser's time zone, based on the device settings. A VPN or a travel setting can change it.

To avoid the problem, check the time zone setting on the calendar site, compare a known release with its actual spike on the chart, and make a note of the offset. A single check each month, especially around clock changes, is enough.

It's boring and it works.

Has a miscalculated news time ever left a position open during a release?

This got me last spring, and it was exactly the window you describe. My calendar site had quietly switched to showing times based on the laptop clock, and I had been travelling the week before, so the laptop was still set to the wrong zone. I was long GBPUSD thinking retail sales was forty minutes out when the candle exploded underneath me.

What I do now is keep one fixed reference that never changes, which is the release time in New York time written on a sticky note next to the monitor for the big US prints. Then each Monday I check one release from the previous week against the actual spike on my M1 chart and confirm the offset between that note, my calendar and the broker server clock.

The weeks between the European and US clock changes get a red line on my paper calendar. During those weeks I widen my news blackout by ten minutes on both sides, because I would rather miss a trade than trust a number I only half verified.
