Endpoint email date and time

Is it possible to include the date and time as data fields using curly brackets {} ?

I have a temperature sensor and want to send an email when temp goes below a certain temp.

I know I can include the temperature data value by using the data name in curly brackets i.e. {mytemp}.

Ideally I want to send an SMS but that require a bit more homework about IFTT I think.
