Is there a difference in meaning or usage between timeline and chronology?

Chronology has a longer history, popping up before 1600 and originally referring to a study of and categorization of time. Timeline appeared first in 1890 according to the OED and was literally a line drawn by a pen. Strictly speaking chronology might have less of a transference to its current usage, but in most every day situations either one would do (my humble opinion).

I think there is a difference, that I can not defend with cite's or confirmation.A pragmatic distinction that can be drawn is that the ' time line ' can connote the "time" between events as long or short, where as the chronological "list" must be interpolated for the same information. In other words, the linear format says more about the time in between events. One is analogical while the other is digital. If someone says "line" when they mean "list", then it becomes a question of vocabulary and is problematic.

My understanding is that a timeline encompasses both a set of discrete events or processes and the duration of the intervals in between, and can relate equally easily to past events and to anticipated or projected future events. It can therefore be used as a planning or scheduling tool, and can also be the outcome of a systematic planning or forecasting process such as critical path analysis or even game theory.

A chronology, on the other hand, focuses on recording when a set of discrete events occurred in the past, and generally disregards the duration of the intervening periods.

Yes, Erik - SMP (the "School Maths {almost put a 'y' in there} Project") was very fond of using "time-lines" (and number-lines, mass-lines ...) as teaching aids. Many people find spatial representations of number-relationships easier to approach than number-relationships shown merely as numbers. Time intervals, where one has to work in two units in one's head, are well served by this approach.
For example, "A game starts at 10:25 am and ends at 3:10 pm How long does it last?"
looks better if recast:

35 min 4h 10 min
v ---------------- v ----------------- v ------------------ v
10:25 am 11:00 3:00 pm 3:10

After practice, the intention is for the process to be possible for the student without the need for the diagram - indeed, without the need for written working.
In non-maths usage, too, there is often an allusion to a notional time-line or timeline rather than to a hard copy.

Edwin,
HTML standard, I'm afraid. Whitespace is merged to a single space. You can only avoid it by using non-breaking spaces. The code for each space is

If you enclose the whole thing in a pair of

tags, it also appears in Courier New, i.e. monospaced.
