是否有 Ansible 函数可以将日期字符串转换为纪元？

我正在寻找将日期输入变量转换为纪元。我没有看到 Ansible 函数可以帮助我解决这个问题。

For eg:

日期是一个格式变量：%m/%d/%Y %H:%M:%S，这需要转换为纪元秒。

Ansible 有一个to_datetime过滤，记录here。该页面包括以下示例：

# Get total amount of seconds between two dates. Default date format is %Y-%m-%d %H:%M:%S but you can pass your own format
{{ (("2016-08-14 20:00:12" | to_datetime) - ("2015-12-25" | to_datetime('%Y-%m-%d'))).total_seconds()  }}

# Get remaining seconds after delta has been calculated. NOTE: This does NOT convert years, days, hours, etc to seconds. For that, use total_seconds()
{{ (("2016-08-14 20:00:12" | to_datetime) - ("2016-08-14 18:00:00" | to_datetime)).seconds  }}
# This expression evaluates to "12" and not "132". Delta is 2 hours, 12 seconds

# get amount of days between two dates. This returns only number of days and discards remaining hours, minutes, and seconds
{{ (("2016-08-14 20:00:12" | to_datetime) - ("2015-12-25" | to_datetime('%Y-%m-%d'))).days  }}

使用此过滤器，您可以将日期转换为 UNIX 纪元时间，如下所示：

- debug:
    msg: "{{ ('2019-05-06 15:50:00'|to_datetime).strftime('%s') }}"

这会输出：

TASK [debug] **********************************************************************************
ok: [localhost] => {
    "msg": "1557172200"
}
