Methods
impl PrimitiveDateTime
[src]
pub const fn new(date: Date, time: Time) -> Self
[src]
Create a new PrimitiveDateTime
from the provided Date
and Time
.

feature="std"
only.Create a new PrimitiveDateTime
with the current date and time (UTC).

Create a PrimitiveDateTime
from the provided Unix timestamp.
