Как добавить собственный календарь торговли в Zipline

Это может быть очень поздно, но это для людей, которые могут наткнуться на эту проблему и могут захотеть использовать внешний пакет для синтаксического анализа строки даты.

Я пробовал искать библиотеки, и я нашел это:

https://github.com/araddon/dateparse

Пример из README:

package main

import (
    "flag"
    "fmt"
    "time"

    "github.com/apcera/termtables"
    "github.com/araddon/dateparse"
)
