could someone pls check where this function is on your sql server server?
I searched the crm installation folder. There are several functions calling this function at the folder: C:\Program Files\Microsoft Dynamics CRM\LangPacks\1033\sql\5.0\StoredProcedures\MSCRM.
eg, dbo.fn_GetFiscalPeriodAndYearCLR, dbo.fn_GetFiscalPeriodCLR.
All the files with the definitions of these functions were last modified 10/26/2010. THis means that the function dbo.fn_ConvertUtcToSpecificTimeCLR must have been created not later from any updates.
Even it was created in an assembly, we should see it show up in database/programmability/functions.
Thanks,
