time travel - Does the Doctor come from the future or the past?

With all the time travel, it's hard to tell. I made a quick search and the information is not available in Wikipedia and TARDIS.wikia. (Well, if it's there, I missed it.)

Are there any clues that could indicate whenever the doctor came from?

Answer

He is from the future.

• The Doctor fought on the front lines [of the time war]and was present at the Fall of Arcadia.¹


• The Fall implies Arcadia is destroyed.


• Arcadia is a planet colonised by humans in the 25th century, and the setting of the Virgin New Adventures novel Deceit.

So if the Doctor fought on the front lines of the time war in the 25th century, then the time war was in the future. The Time War concluded with destruction/time locking of the Gallifreyans and Daleks, which we know is in his past. He has come back from the future for his adventures in the 'present day'.

^{1. According to the Tenth Doctor in Doomsday (2006).}

During the Time War, time was abused. Badly. Because of this there is no way to tell what times it was fought in, with time becoming something easily traveled periods in time can be considered warzones as easily as different planets. The war may have originated in the past, traveled into the future and then been finished. Or the reverse could be true. We simply don't have enough information for a complete answer. We might guess that it is some time before the end of the universe as this is where the Master jumps to in his human form, to avoid his place in the time war.
