Thank you, Amit. I'll run some tests on your list and let you know what I find. Roger is busy today but he might have a chance to do the same later this evening (our time in the USA).

Can I make a constructive criticism? When making tables of data, you should be consistent in how you format things. For example, your dates are written in at least 5 different ways. It makes it very hard to import into a spread sheet or our analysis software. I have to manually fix all the date formats. I am being careful, but mistakes can happen.

I realize different countries and cultures have different ways of writing dates. In the USA we tend to write month/day/year, so today is 11-4-13. In Britain, it's day/month/year, so today is 4-11-13. This can be confusing for either of us because both sets of numbers can be valid dates in both systems.

For scientific work, I prefer to write dates in order of significance - year/month/day. I also forgo any separators, so today to me is 20131104. This naturally extends to include time - year/month/day/hour/minute/seconds - so right now for me it's 20131104173442 (local pacific time). Such numbers are very easy for computers to work with.

To get really detailed, convert from your local time zone to UTC. India is +5hr30m. So subtract 5-1/2 hours from your local time to get UTC. (You are in India, right? Sorry if I'm wrong.)

Which does beg a question, are your dates assuming India Standard Time? I can convert easily if they are. I just need to know so my analysis is accurate.

Just trying to help. It's not only easier for us, but makes you look better, too!
