# Time convention vs time domain, what is the difference?

I really think those are the same thing, but couldn't be so sure.

Is there any difference between time convention and time domain?

For example: "wave propagates along x direction with $$e^{jwt}$$ time convention"

Here, does "time convention" mean time domain?

($$e^{jwt}$$: $$t$$ here means time)

• You will need to give us more context. Neither of these are standard phrases, so the meaning will depend on what context they are being used in. – DJClayworth Apr 7 at 18:45

• In math and physics, the domain of a function of is the set of all inputs, and it is very common to refer to a function as being in the time domain if it is a function of time (that is, it accepts all time values as inputs). I have never heard of "time convention" in a physics context and it has no meaning to me - where did you get that phrase from? – Canadian Yankee Apr 7 at 19:22
• This isn't a basic language question, it is a technical one. As such, it is more appropriate for a technical SE site (such as Physics) where people with knowledge of these technical terms can be found. – Spencer Apr 7 at 19:25
