Working with Time Zones in SSRS

Question

We store all our dates SQL Server 2008 database in UTC time in DateTime columns. I\'m using SSRS to create reports and I need to convert all the times on the reports to th

Answer 1

I figured it out. In the SSRS report, I've added a reference to the assembly System.Core

Then anywhere I needed to convert the timezone I used:

=Code.FromUTC(Fields!UTCDateFromDatabase.Value, Parameters!TimeZone.Value)

where Parameters!TimeZone.Value is the string value of the timezone which can be retrieved in the application by using TimeZone.CurrentTimeZone.StandardName

I should probably put what FromUTC does:

Shared Function FromUTC(ByVal d As Date, ByVal tz As String) As Date
 Return (TimeZoneInfo.ConvertTimeBySystemTimeZoneId(d, TimeZoneInfo.Utc.Id, tz))
end function

Answer 2

Try using this instead:

=System.TimeZone.CurrentTimeZone.ToLocalTime(Fields!DateTime.Value)

For SSRS reports called from AX 2012, this is what I use.
