time as an independent variable

[jasil]

hi everyone.
I'm running a regression where I'm told to include TIME as an independent variable. So my question is: should I state the values of this variable as 1,2,... ? and if this is correct this variable wouldnt be stationary so, would I have to look at the first difference?
maybe E views have some resources to create this kind of varaibles, I would really appreciate some suggestions.
thanks a lot.

It's generally fine to include a time trend.

Take a look at the EViews function @trend for creating one.
