Basic datemath operation for relative time from string, in clojure based of java time.

Require and use:

(require '[datemath.core :as dm])

(dm/calc "now/w +15d -1s") #_"Return a java.time.ZonedDateTime of the proper date"
(dm/calc "2019-01-02T00:10:30Z||/w +15d -1s") #_"Also support iso zoned date string"

Available operations:

• + add time units
• - remove time units
• / round to/truncate to time unit lower boundary

Available units:

• s for seconds
• m for minutes
• h for hours
• d for days
• w for weeks
• M for months
• y for years

You should always start with now or an ISO formated with timezone info such as 2019-01-02T00:10:30Z or 2019-01-02T00:10:30+00:00, it will use timezoned date time.
