2025-12-12 1104092：21：07（2025年12月12日 ｜ 1104092 ｜ 21：07）
That doesn’t look like a valid timestamp. After the date, the time part 1104092:21:07 isn’t a standard time (hours can’t be 1104092).
Did you mean one of these?
- 2025-12-12 11:04:09
- 2025-12-12T11:04:09Z
- 2025-12-12 11:04:09.221007 (time with microseconds) 
- Two times concatenated: 11:04:09 and 2:21:07 
What would you like me to do once we clarify it—validate/normalize it, convert to another timezone/format, or compute a duration?
