In this program, we will get the current LOCAL date-time and print date-time into 12-hour format using the hour12() function.
Add Chrono date-time external library to your project
- Create your project using the below command.
 $cargo new datetime -bin 
- Goto the project folder cd datetime and edit Cargo.toml file.
 $datetime>nano Cargo.toml 
- Then add dependency in Cargo.toml file
 [dependencies]
chrono = "0.4" 
- After that, build your project using the below command
 $datetime>cargo build 
- Then execute your project after modification in src/main.rs source file.
 $datetime>cargo run 
 
                            
Program/Source Code:
The source code to print time in 12-hour format is given below. The given program is compiled and executed on UBUNTU 18.04 successfully.
Output:
$datetime> cargo run Compiling datetime v0.1.0 (/home/arvind/Desktop/rust/datetime) Finished dev [unoptimized + debuginfo] target(s) in 0.29s Running `target/debug/datetime` Local time: 2021-10-30 09:12:53.266391074 -07:00 UTC time: 2021-10-30 16:12:53.266391074 UTC Current time in RIO(Brazil): 2021-10-30 14:12:53.266391074 -02:00Explanation:
In the above program, we imported the "Chrono" library to our project for performing date and time operations. We imported the Chrono library using the below line:
In the main() function, we got the current LOCAL date-time using the Local::now() method and converted date-time in 12-hour format using the hour12() function and printed "AM", "PM" using isPm() function.
