How to convert Unix timestamp to Datetime in Rust

🎈 🎈 🎈


    //First, add the chrono crate to your Cargo.toml:

    [dependencies]
    chrono = "0.4"

    //Then, in your Rust code:

    use chrono::{NaiveDateTime, TimeZone, Utc};

    fn main() {
        let unix_timestamp: i64 = 1366627714; 
        let naive_datetime = NaiveDateTime::from_timestamp(unix_timestamp, 0);
        
        // Convert to UTC
        let datetime_utc = Utc.from_utc_datetime(&naive_datetime);

        println!("Converted Date: {}", datetime_utc);
    }

Output:

Converted Date: 2013-04-22 10:48:34

Example only. There may be multiple ways to perform this operation.

Code Explanation

In this Rust code snippet, the Unix timestamp 1366627714 is converted to a NaiveDateTime object using NaiveDateTime::from_timestamp, where the second argument '0' represents nanoseconds (set to 0 for simplicity).
This NaiveDateTime object is then converted to a UTC datetime using Utc.from_utc_datetime. The resulting date and time are printed in a human-readable format, such as 2013-04-22 10:48:34 in this case.

Other useful Rust date functions (with chrono crate)

Function	Description	Example
`NaiveDateTime::from_timestamp()`	Creates a `NaiveDateTime` object from a Unix timestamp (seconds since 1970) and nanoseconds.	`NaiveDateTime::from_timestamp(1514764800, 0)` returns 2018-01-01 00:00:00
`Utc.from_utc_datetime()`	Converts a `NaiveDateTime` object to a UTC datetime.	`Utc.from_utc_datetime(&naive_datetime)` converts 2018-01-01 00:00:00 to UTC.
`NaiveDate::from_ymd()`	Creates a `NaiveDate` object from the specified year, month, and day.	`NaiveDate::from_ymd(2018, 7, 15)` returns 2018-07-15
`NaiveDateTime::and_hms()`	Adds hours, minutes, and seconds to a `NaiveDate` to create a `NaiveDateTime` object.	`date.and_hms(12, 30, 45)` adds time to a date.
`NaiveDateTime::timestamp()`	Returns the Unix timestamp for a `NaiveDateTime` object.	`naive_datetime.timestamp()` returns 1531656645 for 2018-07-15 12:30:45
`NaiveDateTime::format()`	Formats a `NaiveDateTime` object as a string.	`naive_datetime.format("%Y-%m-%d %H:%M:%S")` returns 2018-07-15 12:30:45
`Utc::now()`	Returns the current UTC date and time.	`Utc::now()` returns the current UTC date and time.
`Local::now()`	Returns the current local date and time.	`Local::now()` returns the current local date and time.
