  • In ABP, AbpClockOptions only lets you choose the kind (Utc, Local, Unspecified). It does not support setting IClock to an arbitrary timezone like “EST”, so Clock.Now cannot be made to directly return “EST time”.
  • The recommended approach is:
    1. Keep AbpClockOptions.Kind = DateTimeKind.Utc (store/process in UTC).
    2. Use ABP’s timezone feature to convert UTC to the user/tenant/application timezone when you need to display or work with “local” times.

  What to do instead (EST example):

  1. Enable UTC clock (as you already do):

  Configure<AbpClockOptions>(options =>
     {
         options.Kind = DateTimeKind.Utc;
     });
  

  2. Set the timezone via the ABP setting Abp.Timing.TimeZone (user/tenant/app level). Then:
     • Use Clock.ConvertToUserTime(utcDateTime) to get the time in the configured timezone.
     • Use Clock.ConvertToUtc(userDateTime) when taking user input and persisting.

  So your code should typically look like:

  var utcNow = Clock.Now; // UTC (when Kind = Utc)
  var estNowForUser = Clock.ConvertToUserTime(utcNow); // converted using Abp.Timing.TimeZone

  If I set app or tenant level to EST, and get datetime value from database, which method I should call to Convert Utc to EST time?

  • If your DateTime value coming from the database is UTC (which is the typical/recommended setup when AbpClockOptions.Kind = DateTimeKind.Utc), then to get it in the configured timezone (app/tenant/user via Abp.Timing.TimeZone, e.g. EST), call:

  var estTime = Clock.ConvertToUserTime(utcDateTime);
  

  Example (entity loaded from DB):

  var entity = await _repo.GetAsync(id);
  
  // entity.SomeTime is assumed UTC
  var estTime = Clock.ConvertToUserTime(entity.SomeTime);
  

  Notes (important):

  • ConvertToUserTime(DateTime dateTime) only converts if:
    • multi-timezone support is enabled (i.e., AbpClockOptions.Kind = DateTimeKind.Utc so IClock.SupportsMultipleTimezone == true), and
    • dateTime.Kind is Utc.
  • The returned DateTime will have Kind = Unspecified (as shown in ABP’s examples), because it represents “user/local” time without embedding timezone in DateTime.

  If you are using DateTimeOffset properties, you can also use:

  var estTimeOffset = Clock.ConvertToUserTime(dateTimeOffset);
