pub fn iso_to_epoch(s: &str) -> Result<u64, String>Expand description
Parse an ISO-8601 / RFC 3339 timestamp into Unix-epoch seconds.
Accepts the formats pylon emits (epoch_to_iso shape) plus the
common RFC 3339 variants users send through the API:
YYYY-MM-DDTHH:MM:SSZYYYY-MM-DDTHH:MM:SS.fffZ(fractional seconds dropped)YYYY-MM-DDTHH:MM:SS+HH:MM/-HH:MM(offset applied)
Hand-rolled to keep pylon-kernel std-only — no chrono dep. Used
by the Postgres adapter to bind TIMESTAMPTZ columns from JSON
strings; SQLite stores them as TEXT and never needed parsing.
