I believe the OP is interested in merging like lines in files in a manner congruent to a paste(1) or join(1), and not cat(1). My understanding is that none of the lines in any file need to be skipped and that the first comma-delimited field is a key (although since all files use the same order, a solution may not need to inspect it) which needs to be removed from all but the first file's line to avoid redundant fields in each line in the final output.

Perhaps something along these lines:
Where <tab> represents a literal tab character and I have assumed that there are no tabs in your source files. If there are, you can choose a suitable delimiter by informing paste with the -d option and using it instead of a tab in the sed command.
Hi,
I want to merge files which belong to the same date in a directory.
For ex:
The below two files are modified on 24 Apr 2007.
SystemOut.log
SystemOut_07.04.24_19.46.40.log
The merged file should be of the format SystemOut.log.2007.04.24 (1 Reply)

processcsv.py
PROCESSCSV.PY(1) Virtualization Support PROCESSCSV.PY(1)NAME
processcsv.py - process virt-top CSV files
SUMMARY
virt-top --csv data.csv
processcsv.py < data.csv
DESCRIPTION
virt-top is a top(1)-like utility for showing stats of virtualized domains.
processcsv.py is a simple Python script that post-processes the output of "virt-top --csv".
It is used like this:
virt-top --csv data.csv
processcsv.py < data.csv
The second command will overwrite the following files in the current directory:
"global.csv"
This contains the global (host) statistics columns from the CSV file.
"domainNN.csv" (multiple files)
For each libvirt domain ID NN, a file is created containing the per-domain statistics from the CSV file.
