Time Zone Conversion Settings
Time Zone Offset Transformation
Transparent mathematical methodology explained in plain English.
Target Local Time = Source Local Time - Offset(Source, UTC) + Offset(Target, UTC)Transforms wall-clock time into UTC epoch coordinates, then projects the instant into target timezone rules accounting for active Daylight Saving transitions.
Variables Explained:
- Source: Starting IANA timezone.
- Target: Destination IANA timezone.
Real Project Example
Convert 2:00 PM (14:00) New York (EDT) to London (BST)
Converting across transatlantic business hours.
Sample Project Inputs:
Date:2026-06-15
Time:14:00
From:America/New_York (UTC-4)
To:Europe/London (UTC+1)
Step-by-Step Calculation:
- New York EDT offset: UTC - 4 hours.
- London BST offset: UTC + 1 hour.
- Time difference: +5 hours ahead.
- 14:00 (2:00 PM EDT) + 5 hours = 19:00 (7:00 PM BST).
Calculated Answer:7:00 PM (19:00 BST) on the same day (+5 hours difference).
