I still think, unless you're investing a constant amount of money every X period, you're timing the market, since you're still subconsciously or consciously picking when to invest into the market depending on time.

The pitfall with "Thinking the market generally goes up and one should invest in it is not timing" is, the thought only occurs after the market has gone way up, rather than occurring unbiasedly between instances when the market has gone way down or way up.
