CSV Feed Timestamp Bug

[jengelman]

Built from master, tried running the bid-ask datafeed example, and got the following results:

   1: 2010-02-03T23:59:59.999989 - Bid 0.5346 - 0.5347 Ask
   2: 2010-02-03T23:59:59.999989 - Bid 0.5343 - 0.5347 Ask
   3: 2010-02-03T23:59:59.999989 - Bid 0.5543 - 0.5545 Ask
   4: 2010-02-03T23:59:59.999989 - Bid 0.5342 - 0.5344 Ask
   5: 2010-02-03T23:59:59.999989 - Bid 0.5245 - 0.5464 Ask
   6: 2010-02-03T23:59:59.999989 - Bid 0.5460 - 0.5470 Ask
   7: 2010-02-03T23:59:59.999989 - Bid 0.5824 - 0.5826 Ask
   8: 2010-02-03T23:59:59.999989 - Bid 0.5371 - 0.5374 Ask
   9: 2010-02-03T23:59:59.999989 - Bid 0.5793 - 0.5794 Ask
  10: 2010-02-03T23:59:59.999989 - Bid 0.5684 - 0.5688 Ask 

In the source data file, every line has a different timestamp. I ran into the same issue with my own bid-ask data, looks like an issue with the timestamp() function in linebuffer.py.

You probably want to share your instantiation of the CSV Feed with the forum ... it may not be a bug after all.

In the meantime you may want to check the FAQ: https://community.backtrader.com/topic/381/faq.

And specifically the remarks about timeframe and compression
