Converting a time interval value for formatting "hh: mm Am / Pm" using C #

Question

I have a value stored in a variable of type System.TimeSpan as follows.

 System.TimeSpan storedTime = 03:00:00; 

Is it possible to save it in another variable of type String as follows?

 String displayValue = "03:00 AM"; 

And if the variable storedTime matters

 storedTime = 16:00:00; 

then it should be converted to:

 String displayValue = "04:00 PM"; 

Answer 1

You can do this by adding your time span to the date.

 TimeSpan timespan = new TimeSpan(03,00,00); DateTime time = DateTime.Today.Add(timespan); string displayTime = time.ToString("hh:mm tt"); // It will give "03:00 AM"

very simple using string format

on .ToSTring("") :

• if you use "hh" →> Hour, using a 12-hour clock from 01 to 12.

• if you use "HH" →> Hour, using a 24-hour clock from 00 to 23.

• if you add "tt" →> Designation Am / Pm.

conversion example from 23:12 to 11:12 Pm:

  DateTime d = new DateTime(1, 1, 1, 23, 12, 0); var res = d.ToString("hh:mm tt"); // this show 11:12 Pm var res2 = d.ToString("HH:mm"); // this show 23:12 Console.WriteLine(res); Console.WriteLine(res2); Console.Read(); 

Wait a second, that not all you need to take care of something else is the Culture system, because the same code is executed in windows with a different langage especialy with a different culture langage will generate an excellent result with the same code

An example of windows installed in an Arabic language culture would look like this:

// 23: 12 م

م means Evening (first leter of مساء).

in another system culture it depends on what is set on the regional and language options of Windows, it will display // 23:12 du.

you can change between different formats on the Windows control panel under regional and language versions of Windows → the current format (combobox) and change ... apply it, rebuild (execute) your application and see what iam is talking about.

so who can I make Am and Pm show in English if the culture of the current system is not installed in English?

easy by simply adding two lines: →

the first step is to add using System.Globalization; on top of your code

and a modification of the previous code will look like this:

  DateTime d = new DateTime(1, 1, 1, 23, 12, 0); var res = d.ToString("HH:mm tt", CultureInfo.InvariantCulture); // this show 11:12 Pm 

InvariantCulture => using the standard English format.

One more question: do I want pm to be in Arabic or a specific language, even if I use Windows installed in a regional (or other language) regional format?

Soution for Arabic Exemple:

  DateTime d = new DateTime(1, 1, 1, 23, 12, 0); var res = d.ToString("HH:mm tt", CultureInfo.CreateSpecificCulture("ar-AE")); 

it will show // 23:12 م

if my system is set to English. you can change "ar-AE" if you want to use a different format. There is a list of each language and its format.

examples: ar ar-SA Arabic ar-BH ar-BH Arabic (Bahrain) ar-DZ ar-DZ Arabic (Algeria) ar-EG ar-EG Arabic (Egypt)

...

Make me know that you have another question.

Answer 3

You can add TimeSpan to DateTime , for example:

 TimeSpan span = TimeSpan.FromHours(16); DateTime time = DateTime.Today + span; String result = time.ToString("hh:mm tt"); 

Demo: http://ideone.com/veJ6tT

 04:00 PM 

Standard Date and Time Format Strings

Answer 4

Fulfilling some answers to existing answers here:

 public static string ToShortTimeSafe(this TimeSpan timeSpan) { return new DateTime().Add(timeSpan).ToShortTimeString(); } public static string ToShortTimeSafe(this TimeSpan? timeSpan) { return timeSpan == null ? string.Empty : timeSpan.Value.ToShortTimeSafe(); } 

Answer 5

 string displayValue="03:00 AM"; 

This is a point in time, not a duration (TimeSpan).

So, something is wrong with your basic design or assumptions.

If you want to use it, first you need to first convert it to a DateTime (point in time). You can format DateTime without the date part, which would be your search string.

 TimeSpan t1 = ...; DateTime d1 = DateTime.Today + t1; // any date will do string result = d1.ToString("hh:mm:ss tt"); 

The storeTime variable may have a value, for example, storeTime=16:00:00;

No, it can have a value of 4 hours, but the presentation is binary, TimeSpan cannot record the difference between 16:00 and 4 pm .

Answer 6

You will need to get the DateTime object from your TimeSpan , and then you can easily format it.

One possible solution is to add time to any date with a time value of zero.

 var timespan = new TimeSpan(3, 0, 0); var output = new DateTime().Add(timespan).ToString("hh:mm tt"); 

The output value will be "03:00 AM" (for English).

Answer 7

Parse the time to DateTime, and then use Format ("hh: mm: tt"). For example.

 TimeSpan ts = new TimeSpan(16, 00, 00); DateTime dtTemp = DateTime.ParseExact(ts.ToString(), "HH:mm:ss", CultureInfo.InvariantCulture); string str = dtTemp.ToString("hh:mm tt"); 

str will be:

 str = "04:00 PM" 

Answer 8

First you need to convert the time interval to a DateTime structure:

 var dt = new DateTime(2000, 12, 1, timeSpan.Hours, timeSpan.Minutes, timeSpan.Seconds) 

Then you need to convert the value to a string with Short Time format

 var result = dt.ToString("t"); // Convert to string using Short Time format 

Answer 9

 Parse timespan to DateTime. For Example. //The time will be "8.30 AM" or "10.00 PM" or any time like this format. public TimeSpan GetTimeSpanValue(string displayValue) { DateTime dateTime = DateTime.Now; if (displayValue.StartsWith("10") || displayValue.StartsWith("11") || displayValue.StartsWith("12")) dateTime = DateTime.ParseExact(displayValue, "hh:mm tt", CultureInfo.InvariantCulture); else dateTime = DateTime.ParseExact(displayValue, "h:mm tt", CultureInfo.InvariantCulture); return dateTime.TimeOfDay; } 

Answer 10

You can try the following:

  string timeexample= string.Format("{0:hh:mm:ss tt}", DateTime.Now); 

you can remove hh or mm or ss or tt according to your needs where hh hour at 12 h is formate, mm is minutes, ss is seconds, and tt is AM / PM.

Answer 11

You cannot add AM / PM to TimeSpan . In any case, you need to associate the TimaSpan value with DateTime if you want to display the time in a 12-hour clock format.

TimeSpan not intended for use with the 12-hour clock format, because here we are talking about the time interval .

As the documentation says;

A TimeSpan object represents a time interval (length of time or elapsed time) that is measured as a positive or negative number of days, hours, minutes, seconds and fractions of a second. The TimeSpan structure can also be used to represent the time of day, but only if the time is not related to a specific date. Otherwise, use the DateTime or DateTimeOffset structure instead.

Microsoft Docs also describe the following:

The value of A TimeSpan can be represented as [-]d.hh:mm:ss.ff , where an additional minus sign indicates a negative time interval, component d is days, hh is hours measured on a 24-hour clock , mm is minutes, ss - seconds, and ff - fractions of a second.

So, in this case, you can display using AM / PM as follows.

 TimeSpan storedTime = new TimeSpan(03,00,00); string displayValue = new DateTime().Add(storedTime).ToString("hh:mm tt"); 

Side note:
It should also be noted that the TimeOfDay DateTime property is a TimeSpan where it represents

a time interval that represents the fraction of the day that has passed since midnight.
