FIFA发布的世界杯赛程以美东时间计算，比北京时间慢12小时（FIFA公布世界杯赛程采用美东时区，较北京时间晚12小时）

Clarifying user intent

I need to figure out what the user is asking. They mentioned the FIFA World Cup schedule in Eastern Time, which is 12 hours behind Beijing Time. It seems like they might want help with converting times or asking for confirmation. I'll need to ask a clarifying question: “Do you want me to convert a specific time, provide a converter, or give instructions?” This will help me understand their exact needs regarding the time difference and daylight saving time.Explaining time differences

I want to clarify the difference in time between Beijing and Eastern Time (ET). When it's Eastern Standard Time (EST), Beijing is 13 hours ahead; during Eastern Daylight Time (EDT), it's 12 hours ahead. So, the user’s statement about being 12 hours behind is accurate only during daylight saving time. I should provide a concise conversion formula and perhaps a small table. Also, I could offer a command-line snippet for conversion in Python or Node if needed. I'll explain this and ask what they specifically require.Providing time conversion options

For the date of December 27, 2025, Beijing is 13 hours ahead of Eastern Time due to winter standard time. While it's important not to rely solely on real-time data, I can confirm this using the system date. I should mention the conversion rules: in winter, Beijing is Eastern Time + 13 hours, and in summer it's +12 hours. I could offer the user help with converting schedules into Beijing time, asking if they'd like me to convert a text or CSV file. Additionally, I could suggest a small script using PyTZ or dateutil if they need code.Summarizing time differences with examples

I should include a quick outline of daylight saving time (DST) months: typically from the second Sunday in March to the first Sunday in November, the difference is 12 hours; otherwise, it's 13 hours. I can provide simple examples, like why New York time on July 1, 8 PM ET equals Beijing time on July 2, 8 AM, while December 1, 8 PM ET equals December 2, 9 AM in Beijing. I'll clarify the 12-hour difference only applies during EDT, then provide a conversion formula and Python and JS snippets for code. I'll keep it brief!

你这句话只在美国夏令时期间成立。北京时间(UTC+8)与美东时间的时差是：

• 夏令时 EDT（约每年3月第2个周日至11月第1个周日）：北京时间比美东快12小时
• 冬令时 EST（其余时间）：北京时间比美东快13小时

现在是冬令时，则应加13小时。换算口诀：

• 北京 = 美东 + 12h（EDT）
• 北京 = 美东 + 13h（EST）

需要我把你手头的赛程批量换算成北京时间吗？发我列表（含日期与美东时间），我可按时区自动处理。
