Commute to airports (Moscow)

Hello,
For my upcoming job in Moscow, there is a chance that the company will move to a llocation close to an airport (Sheremetyevo / Domodeovo / other?) in a year or maybe longer.
I m counting on getting a flat in the center of town as the company is in the center of town right now.
Anybody an idea how much of a commute it would be in the morning and in the evenigng to the airports?
Thanks for any clever hints..
Can
