If I am following you correctly, this is probably a sorting problem. 
Sort the times as ctimes in numerical, not alphabetical order. Since:

	99999999 < 1000000000
	"999999999" > "1000000000"

Where "" indicates a string. In perl (and I know you're using bash), the 
difference is `sort ($a $b)` (default alphabetical) versus 
`sort {$a <=> $b} ($a $b)` (numerical).

What exact command did you use?

Perhaps.
