ccxt检索历史行情如何设置时区？

Question

下面来自 ccxt 的 python 示例将获取历史报价。

https://github.com/ccxt/ccxt/blob/master/examples/py/binance-fetch-ohlcv-to-csv.py

代码没有显示如何设置时区。如何将获取的报价时间戳设置为亚洲 HK/Singapore 时区？

我正在使用 python 3.9

Answer 1

我认为您可以将 2017-08-17T00:00:00+08:00 等时区的日期时间字符串从 your example 传递到 scrape_candles_to_csv 函数（[亚洲 HK/Singapore 有 UTC+8 时区）

方法exchange.parse8601 正确处理了带时区的字符串

>>> exchange.parse8601('2017-08-17T00:00:00+08:00')
1502899200000
>>> exchange.parse8601('2017-08-17T00:00:00Z')
1502928000000

所以我运行

scrape_candles_to_csv('binance.csv', 'binance', 3, 'BTC/USDT', '1h', '2021-12-17T00:00:00+08:00', 100)

得到了

100 candles in total from 2021-12-16T16:00:00.000Z to 2021-12-20T19:00:00.000Z
200 candles in total from 2021-12-16T16:00:00.000Z to 2021-12-24T23:00:00.000Z
260 candles in total from 2021-12-16T16:00:00.000Z to 2021-12-27T11:00:00.000Z
260 candles in total from 2021-12-16T16:00:00.000Z to 2021-12-27T11:00:00.000Z
Saved 260 candles from 2021-12-16T16:00:00.000Z to 2021-12-27T11:00:00.000Z to binance.csv
