It worked. Thanks a lot.
Code:
$sed  's/\(-[^-]*-[^-]*\)-/\1 /g; s/^\([^,]*,[0-9]\{4\}\)\([0-9]\{2\}\)\([0-9]\{2\}\)/\1-\2-\3/' test1
"1912108",2016-11-30,"2016-12-01 00.00.00.000000","2016-12-01 08.37.12.000000"
"1912108",2016-12-01,"2016-12-02 00.00.00.000000","2016-12-02 08.28.22.000000"

This worked well with timestamp columns (3 and 4).
In my flat file, even though I have them numbered as 64 and 65 th columns.

I am trying to tweak this logic to make it work (without success) - with other flat file that has the date column (field 2) as a field 3:-

Code:
"1080909","ABC",20161031,"2016-09-02-00.00.00.000000","2016-09-02-08.30.05.000000"
"1080091","XYZ",20160830,"2016-11-02-00.00.00.000000","2016-11-02-08.27.48.000000"

I am very new to AWK and SED. Can you please help.

vcf-isec [OPTIONS] file1.vcf file2.vcf ... DESCRIPTION
About: Create intersections, unions, complements on bgzipped and tabix indexed VCF or tab-delimited files. Note that lines from all files can be intermixed together on the output, which can yield unexpected results. OPTIONS
-C, --chromosomes <list|file> Process the given chromosomes (comma-separated list or one chromosome per line in a file). -c, --complement Output positions present in the first file but missing from the other files. -d, --debug Debugging information -f, --force Continue even if the script complains about differing columns. -o, --one-file-only Print only entries from the left-most file. Without -o, all unique positions will be printed. -n, --nfiles [+-=]<int> Output positions present in this many (=), this many or more (+), or this many or fewer (-) files. -p, --prefix <path> If present, multiple files will be created with all possible isec combinations. (Suitable for Venn Diagram analysis.) -t, --tab <chr:pos:file> Tab-delimited file with indexes of chromosome and position columns. (1-based indexes) -w, --win <int> In repetitive sequences, the same indel can be called at different positions. Consider records this far apart as matching (be it a SNP or an indel). -h, -?, --help This help message. EXAMPLES
