Struct TimestampMs

pub struct TimestampMs(/* private fields */);

The number of milliseconds since the UNIX_EPOCH.

• Internally represented by a non-negative i64 to ease interoperability with some platforms we use which don’t support unsigned ints well (Postgres and Dart/Flutter).
• Can represent any time from January 1st, 1970 00:00:00.000 UTC to roughly 292 million years in the future.
