A proposed wiki convention for time, which hopes to eventually "date" all the events the story covers with a single time-line.
 Wanda Time
WT stands for "Wanda Time"
Because Wanda is the central character of the story and is present for all the events we have thus far witnessed, it makes sense to mark all turns from the point of her popping. Presently we do not know how long after her popping the Battle of Warchalking occurred, but hopefully someday we will be able to measure all Erfworld events relative to Wanda's life, replacing the need for BW and AW time.
