How To Calculate Time Difference Between DateTime Objects
To get time difference you need to use TimeSpan object, with code like this:
TimeSpan ts = DateTime1 - DateTime2;
For example, if you want to calculate time difference between server time and UTC time:
[ C# ]
protected
void Page_Load(object
sender, EventArgs e)
{
// Declare and get DateTime values
DateTime StartDate = System.DateTime.Now;
DateTime EndDate = System.DateTime.UtcNow;
// Find time difference between two dates
TimeSpan TimeDifference = StartDate -
EndDate;
// Write difference in hours and minutes
Response.Write("Time
difference between server time and Coordinated Universal Time (UTC) is "
+
TimeDifference.Hours.ToString() + " hours ");
if (TimeDifference.Minutes != 0)
Response.Write(" and " +
TimeDifference.Minutes.ToString() + " minutes.");
}
[ VB.NET ]
Protected
Sub Page_Load(ByVal
sender As Object,
ByVal e As
System.EventArgs) Handles
Me.Load
' Declare and get DateTime values
Dim StartDate As
DateTime = System.DateTime.Now
Dim EndDate As
DateTime = System.DateTime.UtcNow
' Find time difference between two dates
Dim TimeDifference As
TimeSpan = StartDate - EndDate
' Write difference in hours and minutes
Response.Write("Time
difference between server time and Coordinated Universal Time (UTC) is "
& _
TimeDifference.Hours.ToString() & " hours ")
If TimeDifference.Minutes <> 0
Then
Response.Write(" and " &
TimeDifference.Minutes.ToString() & " minutes.")
End If
End
