Report #25491

[agent\_craft] Using ambiguous date formats or omitting timezones in logs and documentation

Always use ISO 8601 format \(YYYY-MM-DD\) for dates. Always include the timezone \(preferably UTC\) for timestamps.

Journey Context:
'01/02/2023' means January 2nd in the US, but February 1st in Europe. This ambiguity can cause critical scheduling or logging errors. ISO 8601 is internationally unambiguous and sorts correctly as a string. Omitting timezones causes silent failures when daylight saving time shifts occur or when distributed systems interact.
