Accomodating date and time in a single Infoobject

Hi Gurus,

We are getting an R/3 field(2 fields) as "YYYY.MM.DD HH:MM:SS". And we have mapped that fields to a Two IO (CHAR).Data is getting loaded fine,but not getting it in the same format (with required DOTS and COLONS).Is there any routine that I can write for this IO.If any one have it ,please pass it on.

The two info objects are : ZCREATE & CHANGEDAT are mapped to "created_at" & "changed_at".

Please tell me step by step code.

Points wil be assured.

No idea on how to write a routine .

Urs,

Rakesh.
