Conversion failed when converting date and/or time from character string.

Hi All

I have an HL7 message coming in and am attempting to write it an MS SQL db.
The MS SQL db has the MSHMsgDtm defined as MSHMsgDtm(datetime,null)

The error I get back on the is the following: "Conversion failed when converting date and/or time from character string."

If I hard code a value in on the date such as '1998-12-25', it posts.  I did this simply to make sure the rest of my statement was working.

I attempted CONVERT(DATETIME,@MSH.DateTimeOfMessage.Time,101) as well as many other variations. I'm not an SQL guru and am spending a great deal of time trying to figure out the correct syntax. Thanks for any assistance.

INSERT INTO HOSPITAL_Cutover_DFTs (MSHSendApp, MSHSendFac, MSHRecvApp, MSHRecvFac, MSHMsgDtm, MSHCtrlID, PIDIntID, PIDLastName, PIDFirstName, PIDVisitNo, FT1SetID, FT1TransID, FT1TransBatchID, FT1TransPostDtm, FT1TransType, FT1TransCode, FT1TransDesc, FT1TransDescAlt, FT1TransQty, FT1TransAmtExt, FT1TransAmtUnit, FT1DeptCode, FT1PatnLocn, FT1PatnType, FT1DiagCode, FT1PerfByCode, FT1ProcCode)
