datetime的时区转换 1.将时区信息添加到datetime日期时间对象from datetime import datetime from pytz import timezone date_str = "2009-05-05 22:28:15" datetime_obj = datetime.strptime(date_str, "%Y-%m-%d %H:%M:%S") datetime_obj_utc = datetime_obj.replace(tzinfo=timezone('UTC')) print(datetime_obj_utc.strftime("%Y-%m-%d %H:%M:%S %Z%z"))运行结果：2009-05-05 22:28:15 UTC+00002.将非UTC时区信息添加到datetime日期时间对象from datetime import datetime from pytz import timezone date_str = "2014-05-28 22:28:15" datetime_obj_naive = datetime.strptime(date_str, "%Y-%m-%d %H:%M:%S") # 错误的方式❌! datetime_obj_pacific = datetime_obj_naive.replace(tzinfo=timezone('US/Pacific')) print(datetime_obj_pacific.strftime("%Y-%m-%d %H:%M:%S %Z%z")) # 正确的方式✅! datetime_obj_pacific = timezone('US/Pacific').localize(datetime_obj_naive) print(datetime_obj_pacific.strftime("%Y-%m-%d %H:%M:%S %Z%z"))运行结果：2014-05-28 22:28:15 PST-08002014-05-28 22:28:15 PDT-07003.时区转换from datetime import datetime from pytz import timezone fmt = "%Y-%m-%d %H:%M:%S %Z%z" # Current time in UTC now_utc = datetime.now(timezone('UTC')) print(now_utc.strftime(fmt)) # Convert to US/Pacific time zone now_pacific = now_utc.astimezone(timezone('US/Pacific')) print(now_pacific.strftime(fmt)) # Convert to Europe/Berlin time zone now_berlin = now_pacific.astimezone(timezone('Europe/Berlin')) print(now_berlin.strftime(fmt))运行结果：2009-05-06 03:09:49 UTC+00002009-05-05 20:09:49 PDT-07002009-05-06 05:09:49 CEST+02004.查看所有时区from pytz import all_timezones print len(all_timezones) for zone in all_timezones: if 'US' in zone: print(zone)运行结果：US/AlaskaUS/AleutianUS/ArizonaUS/CentralUS/East-IndianaUS/EasternUS/HawaiiUS/Indiana-StarkeUS/MichiganUS/MountainUS/PacificUS/Pacific-NewUS/Samoa

Ubuntu修改系统时区 方法一1 修改时间tzselect 依次选择4->9->1->1 #Asia->China-> Beijing->yes2 复制文件到/etc目录下sudo cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime 3 查看修改结果date -R方法二1.列出可用的中国时区sudo timedatectl list-timezones | grep Asia/Shanghai2.设置中国时区sudo timedatectl set-timezone Asia/Shanghai3.验证时区设置timedatectl
