pub fn parse_datetime_utc(s: &str) -> Result<DateTime<Utc>>Expand description
Parse a datetime string into a DateTime<Utc>.
Supports multiple formats:
- RFC3339 (e.g., “2023-01-01T00:00:00Z”)
- “%Y-%m-%d %H:%M:%S %z” (e.g., “2023-01-01 00:00:00 +0000”)
- “%Y-%m-%d %H:%M:%S” naive (assumed UTC)
This is the canonical datetime parsing function for temporal operations
like validAt. Using a single implementation ensures consistent behavior.
