description = r#"
Converts a value to a timestamp (`YYYY-MM-DDT00:00:00Z`). Supports strings, integer, unsigned integer, and double types as input. Strings are parsed as RFC3339 (e.g. '2023-07-20T05:44:00') if no [Chrono formats] are provided. Integers, unsigned integers, and doubles are interpreted as seconds since the unix epoch (`1970-01-01T00:00:00Z`). Returns the corresponding timestamp.

Note: `to_timestamp` returns `Timestamp(Nanosecond)`. The supported range for integer input is between `-9223372037` and `9223372036`. Supported range for string input is between `1677-09-21T00:12:44.0` and `2262-04-11T23:47:16.0`. Please use `to_timestamp_seconds` for the input outside of supported bounds.
