需要一个带有pytz的ListBox / Dropdown common_timezones命名UTC的每个差异。
<select style="cursor:pointer; min-width: 300px;" name="timezone">
{% for tz in timezones %}
<option value="{{ tz }}"{% if tz == TIME_ZONE %} selected="selected"{% endif %}>{{ tz }}</option>
{% endfor %}
</select>
我正在用以下方式提供该列表: 'timezones':pytz.common_timezones,'TIME_ZONE':request.session ['django_timezone'] 在渲染到响应......
但我只得到一个名单列表..我需要一个名称列表,每个时区的差异为UTC ..
示例:
America / XYZ UTC-xxxx / UTC-xxxx + 1
欧洲/ XPTO UTC + xxxx
已编辑:我很乐意在此时刻(此时此刻)获得每个时区的当前已知偏移量,如果可能的话,可能会有一个/两个去年产生(可能性如下:{{ 3}})。
提前感谢您提供任何帮助!

我来到这个:
def get_timezones_with_gmt_diff(timezone_string_list = None):
"""
Converts a datetime object into string.
"""
if timezone_string_list:
timezone_list = timezone_string_list
else:
timezone_list = pytz.common_timezones
datetime1 = datetime.strptime("10-07-%s 00:00:00" % datetime.utcnow().year, "%d-%m-%Y %H:%M:%S")
datetime2 = datetime.strptime("10-12-%s 00:00:00" % datetime.utcnow().year, "%d-%m-%Y %H:%M:%S")
result_dict = {}
for time_zone in timezone_list:
result_dict[time_zone] = [Date.timedelta_in_seconds(pytz.timezone(time_zone).localize(datetime1).tzinfo._utcoffset)/3600,
Date.timedelta_in_seconds(pytz.timezone(time_zone).localize(datetime2).tzinfo._utcoffset)/3600,
time_zone.replace("/", " - ").replace("_", " "),
Date.timedelta_in_seconds(pytz.timezone(time_zone).localize(datetime1).tzinfo._utcoffset)/3600 !=
Date.timedelta_in_seconds(pytz.timezone(time_zone).localize(datetime2).tzinfo._utcoffset)/3600]
sorted_result_dict = OrderedDict(sorted(result_dict.items(), key=lambda t: t[1][2]))
return sorted_result_dict
def get_timezones_for_listbox(time_zones_dict):
list = []
for time_zone_tuple in time_zones_dict:
# Has different DST/Summer times:
if time_zones_dict[time_zone_tuple][3]:
new_item = "%s UCT %s/%s" % (str(time_zones_dict[time_zone_tuple][2]), str(time_zones_dict[time_zone_tuple][0]), str(time_zones_dict[time_zone_tuple][1]))
# Does not change datetime:
else:
new_item = "%s UCT %s" % (str(time_zones_dict[time_zone_tuple][2]), str(time_zones_dict[time_zone_tuple][0]))
list.append(new_item)
return list
def timedelta_in_seconds(duration):
days, seconds = duration.days, duration.seconds
return days * 24 * 60 * 60 + seconds
当然,我将进一步操作这两种方法,以便从输入上下文中完成所需的输出。

{% load tz %}
<select style="cursor:pointer; min-width: 300px;" name="timezone">
{% for tz in timezones %}
<option value="{{ tz }}"{% if tz == TIME_ZONE %} selected="selected"{% endif %}>
{{ tz }} - {{tz|utc}}
</option>
{% endfor %}
</select>
