Here is what i had in mind...
Code:
awk '{
   n = split($NF, a, ",")
   g = "(....)-(..)-(..) (..):(..):(..),.*$"
   f = "\\1 \\2 \\3 \\4 \\5 \\6"
   d[NR] = gensub(g, f, "", $(NF-1)" "$NF)
   t = mktime(d[NR])
   d[NR] = t * 1000 + a[n]
} END {
   print NR
   for (i=1; i<NR; i+=2)
       print "diff: " d[i+1] - d[i]
}' file

where file contents are...
Code:
$ cat file
Starttime 2013-04-03 08:54:19,989
End time  2013-04-03 08:54:39,389
