How to get UTC time?

Post by dlube »

Hi
If someone can help me ;)
I did this

Code: Select all

 	local Time = require('Time')
        local localTime = Time()
        print(localTime.utcTime.hour)
and I got this

Code: Select all

2020-06-01 15:24:01.179 Error: dzVents: Error: (3.0.2) ...e/pi/domoticz/scripts/dzVents/generated_scripts/Test.lua:12: attempt to index a nil value (field 'utcTime')
What is wrong in my code?

Another way to get for a lua-script the components of the utc-timestring.

Timestring (at the end of the script-segment) is a compilation of components as required for some uploads:
therefore insertion of character 20 as required for complete year-identification, and of separators %20 and %3A.

Code: Select all

-- Line xx, Get Time-related data in UTC
utc_dtime = os.date("!%m-%d-%y %H:%M:%S",os.time())
month = string.sub(utc_dtime, 1, 2)
day = string.sub(utc_dtime, 4, 5)
year = "20" .. string.sub(utc_dtime, 7, 8)
hour = string.sub(utc_dtime, 10, 11); hour_n = tonumber(hour)
minutes = string.sub(utc_dtime, 13, 14); minutes_n = tonumber(minutes)
seconds = string.sub(utc_dtime, 16, 17)

timestring = year .. "-" .. month .. "-" .. day .. "%20" .. hour .. "%3A" .. minutes .. "%3A" .. seconds

Does this help ?

Code: Select all

		local utc = os.date("!*t")
		print('UTC hour is ' .. utc.hour)

I knew this way.
Thank you
However I would like to use the dzVents :)

It seams that the utcTime property of the Time object does not exist.
Is it a bug or not?

No it is magic.. :)

The tables utcSystemTime and utcTime only exist in dzVents time objects where isUTC is true .

Below example

Code: Select all

return 
{
    on = 
    {
        devices = 
        {
            'timeTrigger', -- or any other device
        },
    },

    execute = function(dz)
        isUTC = true
        utcTime = dz.time.makeTime(dz.time.raw,isUTC)
        dz.utils.dumpTable(utcTime)
    end
}
give

Code: Select all

I thought that the property gave you the UTC time from the local time.
As you know that it is an UTC time I do not understand the aim of this property.
Hour, minutes,etc... are already available in the time property hour, minutes, etc
It should be a good function to get the UTC time from the local ;)
Thank you all
