Hi,
I am currently looking into downloading data more intense and I found some behaviour which I do not understand.
I am downloading historical data with the zorro script "Download" and the resulting files (.t6) have overlapping times. This can be reproduced with stocks or CFDs with an IB as well with an OANDA account.

I have the following scenario:
1) I have 10 years plus history of 1min data of the stock AAL
2) the history files are divided by year in my history folder. I bought the history yesterday (see screenshot 1)
3) I am updating the history with the Download script of zorro (see screenshot 2)
4) the updated file has overlapping times AND the times seem to be shifted with the minuted where the download script was started (see screenshots 3x)

I am going to explain point 4 a little more as it is quite unusual and it looks very wired to me.

The message from the zorro window says it is going to download the prices from 10th of September from 00:01 until the minute where I started the script.
BUT the first appended time is 20:18 which is the start time of the script - 4 (Conversion UTC to ET) plus 18 (script start time). I did several tests and it is always the same logic (-4 hours + plus script start time)..

What is going on here? Am I missing something very basic or are we having an issue here?

Any help is appreciated.
Thanks
