I would like to have a @countup@ or @timesince@ variable that would provide the time since a given date & time. Ideally, the output would be in the form of years, months, days, hours. This could be done as an option to the @unixtime@ variable, so that instead of just using @unixtime@ to get seconds since epoch, expand the variable to accept a date and optional time, such as @unixtime@[November 01, 2000 21:30 -0800], and then we could use @calc@ to calculate the years, months, etc.
This is to replace using a similar Moobot variable, that only provides weeks, days, hours, no matter how many years ago the given date and time are.
