Disclaimer: Whatever errors I find may be unrelated to the problem itself as I repeatedly got distracted while writing this comment...

- (A trait of senior monks that's rubbed off on me): use strict - it helps...

- Shouldn't

for ($ii = @time[0]; $ii <= @time[$#time]; $ii++)
[download]

be using $time[0] and $time[$#time]? There are also other lines using that notation...

- In your "Code with DBI" make PrintError=>1 and redirect the output for late night reading ;)

- Check those output files to make sure that there are no "character combinations" that have a special meaning in SQL... It could be where you're losing the data...
