How do i get military time and not the date. currently it returns this.

11/25/2016 1:30:00 AM

I want to see
13:30

C#

var start_time = dateTimePicker1.Text;
var start_time_array = start_time.Split(':');
var today = DateTime.Now;
var trailer_count = Convert.ToInt32(tbTrailer_Needed.Text);
var minutes_apart = Convert.ToDouble(tbTime_Between.Text);
var calculated_start_time = new DateTime(today.Year, today.Month, today.Day, Convert.ToInt16(start_time_array[0]), Convert.ToInt16(start_time_array[1]), 00);

What I have tried:

None of these worked
I have tried Mask and adjusting property.
var time = value.TimeOfDay;

C#

DateTime.Now.ToString("hh:mm:ss")

"1:30:00 AM" is more likely to give "13:30" rather than "14:30"

and 01:30 would be even better

I corrected the typo any suggestions on how to fix it?

There's no such thing as "military time".

In some country, the 24 hours format is called military time because the format in usage is 12 hours format with AP/PM.

If you want military time, you have to use ToString("HH:mm")

Getting error when add to my code. an object reference is required for a non static field, method or property to datetime.ToString(string)

You put the ToString() call on your variable that is tracking your time.

    Console.WriteLine("The time is " + myTime.ToString("HH:mm"));

PIEBALDconsult 26-Nov-16 0:14am

Console.WriteLine("The time is {0:HH\\:mm}" , myTime);

Dave Kreskowiak 26-Nov-16 0:24am

    Console.WriteLine($"The time is {myTime.ToString("HH:mm")}");

PIEBALDconsult 26-Nov-16 1:07am

Console.WriteLine("What have you been smoking?");

Dave Kreskowiak 26-Nov-16 10:42am

Console.WriteLine("WEED! Wanna hit?");

For crap sake, I gotta tell you to do mytime.ToString("HHmm") ? Can't you infer that from my answer?

Solution 2

If you want it as an integer (eg:1330 hours), as it is often used

C#

int time24 = mtTime.Hour * 100 + myTime.Minute;

Why not just:
myTime.ToString("HHmm"); ?

Member 12349103 26-Nov-16 11:23am

I dont know what lines to edit in my code to make it work.

Solution 3

Help yourself to the Custom Date and Time Format Strings[^] in .NET framework.
Specifically, your interested military time (24-hour clock) format is at The "HH" custom format specifier[^].
