带有 CRON 的 volttron 调度执行器代理

Question

对于我使用 agent creation wizard 开发的 volttron 代理，我可以得到与此相关的错误提示吗，'Timezone offset does not match system offset: -18000 != 0. Please, check your config files.'

当使用 from volttron.platform.scheduling import cron 功能测试我的脚本时，我注意到 timezone/computer 时间在我的边缘设备上偏离了，所以我用这个 tutorial 重置了我正在考虑的时区肯定把事情搞砸了。

ERROR: volttron.platform.jsonrpc.RemoteError: builtins.ValueError('Timezone offset does not match system offset: -18000 != 0. Please, check your config files.')

无论这是否有所不同，此边缘设备确实使用转发代理将数据推送到中央 VOLTTRON 实例。

这是我下面的 raise_setpoints_up 函数，它很像 CSV 驱动程序代理代码。

def raise_setpoints_up(self):

_log.info(f'*** [Setter Agent INFO] *** -  STARTING raise_setpoints_up function!')
schedule_request = []

# create start and end timestamps
_now = get_aware_utc_now()
str_start = format_timestamp(_now)
_end = _now + td(seconds=10)
str_end = format_timestamp(_end)

# wrap the topic and timestamps up in a list and add it to the schedules list
for device in self.jci_device_map.values():
    topic = '/'.join([self.building_topic, device])
    schedule_request.append([topic, str_start, str_end])

# send the request to the actuator
result = self.vip.rpc.call('platform.actuator', 'request_new_schedule', self.core.identity, 'my_schedule', 'HIGH', schedule_request).get(timeout=4)
_log.info(f'*** [Setter Agent INFO] *** -  actuator agent scheduled sucess!')

感谢任何提示

Answer 1

我怀疑 tzdata 配置的时间与系统配置的时区不同，因为你手动更改了它。试一试：

sudo dpkg-reconfigure tzdata

Answer 2

使用sudo dpkg-reconfigure tzdata改回UTC时间
