公式
How Time Zone Conversion Works
Each time zone is defined as an offset from UTC (Coordinated Universal Time). To convert, calculate the difference in offsets and add it to the source time.
Formula
Target Time = Source Time + (Target UTC Offset - Source UTC Offset)
If the result is negative, add 24 (previous day). If over 23, subtract 24 (next day).
计算示例
It is 14:00 (2 PM) in UTC-5 (New York). What time is it in UTC+1 (Paris)?
- 01Offset difference = 1 - (-5) = 6 hours
- 02Target time = 14 + 6 = 20:00 (8 PM)
- 03Paris is 6 hours ahead of New York
常见问题
What does UTC mean?
UTC stands for Coordinated Universal Time. It is the global time standard from which all time zones are defined as positive or negative offsets.
What about daylight saving time?
DST shifts the UTC offset by 1 hour during summer months. Check whether your region observes DST and adjust the offset accordingly.
What are common UTC offsets?
US Eastern: UTC-5 (EST) / UTC-4 (EDT). US Pacific: UTC-8 / UTC-7. UK: UTC+0 / UTC+1. Central Europe: UTC+1 / UTC+2. Japan: UTC+9. India: UTC+5:30.
