First, I used the google translation. Please let me know if you can't understand my English.

I wanted my full transaction data in Openledger. I used Node.js and retrieved over 100+ my account history data. I referred to this site.

https://github.com/openledger/openledger_nodejs_api

But, "account history" have a block number but no date.  It's very difiicult for me to derive the every date manually from the every block number using cryptofresh.
Does anybody have any ideas?
