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?
