EventHandler message

    In EventHandler I am getting the following message:

    JavaScript
    {"info": {"ts":1675427367.680000,"tF":77.900000,"tC":25.500000,"event":"temperature_change","id":102,"component":"temperature:102"}, "now":1675427367.679535, "id":102, "name":"temperature", "component":"temperature:102"}

    As I understand "ts" and "now" are Unix time. The question is what is the difference between them? Why Unix time is shown in two places?
