Timer that is increased every 27ms, and counts towards economy time units, expressed in days / months / years.
For now, this is kept in sync with the calendar date, so the amount of days in a month depends on the month and year (leap-years). There are always 74 ticks in a day (and with 27ms, this makes 1 day 1.998 seconds).
Economy time is used for the regular pace of the game, including:
