JWT token Expiration is not getting set to the required time

Question

I'm using JWT in my.Net Core application and I'm using System.IdentityModel.Tokens.Jwt (5.6.0) I'm trying to set the expiration time as follows:

var token = new JwtSecurityToken(
                "www.site.com",
                "www.site.com",
                claims,
                expires: DateTime.UtcNow.AddMinutes(5),
                signingCredentials: credentials);

My computer's time is 2.38 pm and tokens validate to propertys' value is 9.43 pm. Which has to be 2.43 pm.

My Startup.cs configurations are as bellow:

services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme)
        .AddJwtBearer(options =>
        {
            options.TokenValidationParameters = new TokenValidationParameters
            {
                ClockSkew = TimeSpan.Zero,
                ValidateIssuer = true,
                ValidateAudience = true,
                ValidateLifetime = true,
                ValidateIssuerSigningKey = true,
                ValidIssuer = Configuration["Authentication:Issuer"],
                ValidAudience = Configuration["Authentication:Issuer"],
                IssuerSigningKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(Configuration["Authentication:Secret"]))
            };
        });

What is the reason for this? Thank you for your help.

You are living a location where the time zone is UTC -7. DateTime.UtcNow returns UTC time, use DateTime.Now instead.
