In different browsers input time field shows in different formats [duplicate]

This question already has an answer here:

• html5 time inputs shows 12 hours 6 answers

I created an input time HTML element, with this line:

<input type="time" id="startTime" value="@DateTime.Now.ToString("HH:mm")" />

I am using C# Razor syntax, but it does not really matter.

I checked it in both Google Chrome and Mozilla Firefox and in both time is represented in 24 hour format. Later, when I shared the code with my colleagues, in their versions of Chrome the time is represented in 12-hour format with AM and PM. Is there a way to specify in my HTML code that time should be represented in one way in all browsers.

Thank you!
