将Jira获取的UTC时间转本地时间yyyy-MM-dd’T’HH:mm:ss

将Jira获取的UTC时间转本地时间yyyy-MM-dd’T’HH:mm:ss

通过API获得jira 备注(comment)的更新时间,发现获得的UTC时间格式为
2018-08-14T02:52:22.216+0000
这个时候,如果需要转换成datetime :yyyy-MM-dd'T'HH:mm:ss格式,
或者date:yyyy-MM-dd,可以用下面的代码:

#!/usr/bin/python
# -*- coding:utf-8 -*-
import re
import time
from datetime import datetime
def utc2local(utc_st):
    # UTC时间转本地时间(+8:00)
    now_stamp = time.time()
    local_time = datetime.fromtimestamp(now_stamp)
    utc_time = datetime.utcfromtimestamp(now_stamp)
    offset = local_time - utc_time
    local_st = utc_st + offset
    return local_st
def local2utc(local_st):
    # 本地时间转UTC时间(-8:00)
    time_struct = time.mktime(local_st.timetuple())
    utc_st = datetime.utcfromtimestamp(time_struct)
    return utc_st
def utc_format(utcstr):
    """
    将不标准的utc时间字符串转换成datetime格式
    :param utcstr: 不标准的utc字符串,如‘2018-04-23T03:43:35.000+0000’
    :return:
    """
    utcstr = re.sub('.ddd+0000', '', utcstr, count=1)
    try:
        UTC_FORMAT = "%Y-%m-%dT%H:%M:%S"
        d_time = datetime.strptime(utcstr, UTC_FORMAT)
    except Exception:
        UTC_FORMAT = "%Y-%m-%d %H:%M:%S"
        d_time = datetime.strptime(utcstr, UTC_FORMAT)
    return d_time
def get_local_date(utcstr):
    """

    local_date = datetime.strptime(local_str, "%Y-%m-%d")
    # print local_date
    return local_date
def get_local_datetime_str(utcstr):

    return local_str
