Struct tea_dtype::Time

#[repr(transparent)]
pub struct Time(pub i64);

Represents a time of day with nanosecond precision.

This struct is a wrapper around an i64 value representing the number of nanoseconds since midnight. It provides various methods for creating, manipulating, and converting time values.
