Seconds from now to seven o'clock.

Well, @Tap1 you would get DateTime.(Now, Etc) and increase it. Example 7h (*times) 60m = 420 (*times) 60 (capturing the seconds) 25, 200 Alternatively go to google and type in hours to seconds and a t$$anonymous$$ng will pop up that will help you convert it.

EDIT: TRY THIS CODE. @Tap1
using System;

namespace ConsoleApp1 { class Program { static void Main(string[] args) { TimeSpan TillSeven; DateTime date = new DateTime(2017, 7, 31, 7, 00, 0); TillSeven = DateTime.UtcNow - date; Console.WriteLine(TillSeven.Hours 60 60); //4 hour 60 = 240 Minutes 60 = 14,400 Seconds. Console.ReadKey(); } } }
