When you edit a bid, you create a scar in the space-time continuum. According to certain Euclidean space perceptions, the universe has three dimensions of space and one dimension of time. By combining space and time into a single manifold, physicists have significantly simplified a large number of physical theories, as well as described in a more uniform way the workings of the universe at both the supergalactic and subatomic levels.
In classical mechanics, the use of Euclidean space instead of space-time is appropriate, as time is treated as universal and constant, being independent of the state of motion of an observer. In relativistic contexts, however, time cannot be separated from the three dimensions of space, because the rate at which time passes depends on an object's velocity relative to the speed of light and also on the strength of intense gravitational fields, which can slow the passage of time.
Now, as Einstein theorized, space actually bends, relative to what we perceive as gravity. Thus, when you go back to alter a bid, you create a pull on the bid, which bends space, and therefore bends time, which changes the time, and naturally, changes the time of your bid relative to the third dimension, that being Cigarbid itself.
Consequently, even though time appears to have passed at a normal rate to you, it has passed through space to reach Cigarbid, and in doing so, has curved through space. If you were able to follow that, you would theoretically be able to remain in the same location with regards to the timing of your bid. However, no human can move at the same speed as the passage of data through space, ergo you are either stuck with the changed timing, or have to keep the same bid.
That is, of course, unless you can beat the data change to the servers at Cigarbid.
