Updating time of a property in Thingworx using lua

Hi,

Trying to update time of the property on thingworx using following code

ts = 1578034820000    -epoch unix time in miliseconds

local data = {}
data.value = valore
data.time = ts
data.quality = "Good"
me:setProperty(nome, nil, nil, data)

,but except time it is updating value and quality of the property.

Tried to update after converting ts into different formats, but in vain.

Thank you!

Best Regards,

Naeem
