Convert time between different timezones using IANA timezone database. Supports 12/24-hour formats, specific dates, and automatic DST handling.

Convert time between different timezones.

Usage Scenarios

Scenario 1: Cross-Timezone Meeting Time

User input: "纽约上午10点对应北京时间几点？"

Expected output: 2026-06-19 10:00 America/New_York = 2026-06-19 22:00 Asia/Shanghai. Offset: -04:00 (EDT) → +08:00 (CST). Difference: 12 hours ahead.

Scenario 2: Convert to UTC

User input: "伦敦下午2点半转成UTC时间。"

Expected output: 2026-06-19 14:30 Europe/London = 2026-06-19 13:30 UTC (BST active, UTC+1). Offset: +01:00 → +00:00.

Scenario 3: International Call Planning

User input: "东京晚上9点换算到洛杉矶时间。"

Expected output: 2026-06-19 21:00 Asia/Tokyo (JST) = 2026-06-19 05:00 America/Los_Angeles (PDT). Note: this is 5:00 AM same day in Los Angeles. Difference: 16 hours behind.

Scenario 4: 国内外团队会议时间配对

User input: "我上海的，美国那边同事在纽约，我们想每周开一次远程会议，对方说周三上午10点（EST），那是北京时间几点？" Expected output: 进行时区转换：纽约EST（冬令时UTC-5）→北京时间（UTC+8）时差13小时，EST周三上午10点即北京时间周三晚上23点。如果在美国夏令时（EDT，UTC-4），时差12小时，即周三晚上22点。自动识别当前是否夏令时。建议双方各让一步，选在双方都方便的折中时间（如北京时间上午9点=EST前一天晚8点/EDT晚9点）。
