Add time from u64

[Sytten]

PR Info

I migrated our codebase to using time and I had a compilation error on my model:

pub struct Model {
    #[sea_orm(primary_key)]
    pub id: i32,
    #[sea_orm(primary_key, auto_increment = false)]
    pub time: TimeDateTimeWithTimeZone,
    #[sea_orm(column_type = "Text")]
    pub ip: String,
    #[sea_orm(column_type = "Text")]
    pub version: String,
    #[sea_orm(column_type = "Text")]
    pub platform: String,
}

Fixes

• Adds missing TryFromU64 for time objects
