@CrockAgile Thanks!, The PR is almost perfect!
Just few minor suggestions below.

I'd suggest:

• running rustfmt on the example
• dropping the intermediate variables and making the queries directly in the println!body

    let (is_pm, hour) = now.hour12();
    println!(
        "The current UTC time is {:02}:{:02}:{:02} {}",
        hour,
        now.minute(),
        now.second(),
        if is_pm { "PM" } else { "AM" },
    );

The example should ges slightly less noisy.

[CrockAgile]

I agree. Good change

[budziq]

I'd probably avoid using the tpe and trait names in the example title. How about something along the lines of "Examine the date and time"?

[CrockAgile]

Sounds good! I was trying to be explicit toward the issue, but you are right that including it makes it a little verbose/wordy. Thanks for the review

Will it be useful to show also the other way around, i.e. from a string date (example "2017/12/31T12:34:56-1:00") get the DateTime via parse_from_rfc3339 or parse_from_str?

We already have date parsing example I'd suggest to keep this example focused as it is.

The comment repeats what is said in recipe description (few lines above). Does it make sense to remove it (to make example slightly shorter)?

Yeah, this is a good idea.
Lets drop the comments and we are ready to merge!

Also, the example title is still a little off but I can't come up with a better one at the moment. @CrockAgile If you can come up with something slightly more natural please propose one but it will not block the PR.
Well done!

@budziq I also can't get a better title in my head, but I agree it is lacking. "Get current date and time"? I am open to suggestions. Hard to be more detailed/exciting when there are already examples for parsing and modifying datetimes.

My bad, I have not seen it. Thanks!

Thanks @CrockAgile!
