I need help understanding condition damage stat
The effects vary from condition to condition, and are applied on a per-second basis.
If I remember right, half your condition damage is added to burning every second and bleeding gets something around 1/20th of your condition damage every second. The wiki should have accurate information for each condition.

I can’t say for certain and I understand the calculations are a lot more complex than this, but I’ve been going by the assumption that +condition adds to the total amount of condition damage a skill can do, which is then divided by the number of seconds (or ticks) that it runs.
For instance, a poison skill might inflict 1000 condition damage over 5 seconds, for 200/tick. Adding another 100 condition damage (from whatever source) to it would give you 1100 over 5 seconds, for 220/tick.
That’s my understanding of it, which is based on little more than a guess and loose observation. I’d welcome any correction, if any are forthcoming.
According to the wiki, 100 Condition Damage adds
5 damage per second per stack of Bleed (5%),
25 damage per second of Burn (25%),
7.5 damage per attack per stack of Confusion (7.5%), and
10 damager per second of Poison (10%).
