Answer 1

Well, you could start off by using DateTime.UtcNow, transferring that to the client, and then performing the relevant time zone conversions at the client. That's usually a reasonable way of working - so long as you can do the processing at the client (e.g. in JavaScript).

Alternatively, ask the user their time zone so you can serve pages which use the local time, using TimeZoneInfo. Of course if you know all your users are in Egypt you could potentially just hard-code that.

Answer 2

Well, you could use DateTime.UTCNow and then convert to local time.

Answer 3

Generate the time using UTS, so that it is normed, and then display based on the location of the user or on their preferences.

Answer 4

Server time will never be the same as client time.

You can get the client time using javascript:

var currentDate = new Date();

Answer 5

DateTime now = TimeZoneInfo.ConvertTime(DateTime.UtcNow, 
    TimeZoneInfo.FindSystemTimeZoneById("Egypt Standard Time"));

Answer 6

Different regions of the world move the clocks forward or backward at different times. So even if you program a time zone adjustment, you may still have problems.

The idea of getting the client time with javascript seems to offer a solution.

My question is, how do you pass the information obtained with javascript to the server, using ASP.NET?

Thank you in advance.
