word substitution in csh

Shell Programming and Scripting
1

I have data that looks something like this:

term1/term2/2005-12-01 13:20:30/term4

I need to make it look like this:

term1/term2/20051201132030/term4

I am using a csh script. I have tried to do it by first converting the date/time to the format in which I want it, and then replacing it using a tr command to replace the old date/time to the new one, but tr doesn't like strings of different lengths. Is there some other command I can use, or just an easier way of doing this altogether?

Thanks in advance...
