pub fn parse_ib_timestamp(s: &str) -> Option<DateTime<Utc>>Expand description
Parse IB timestamp format (YYYYMMDD HH:MM:SS timezone).
IB sends timestamps like “20250418 10:30:00 US/Eastern”. This function parses the timezone and converts to UTC.
§Fallback Behavior
- Unknown timezone string: treats as UTC (logs warning)
- DST-ambiguous time (during “fall back” transition): returns
None, caller typically falls back toUtc::now(). This affects ~1 second per timezone per year and is unlikely to occur in practice.
