In English, either a date followed by a time, or vice-versa, e.g,
- yesterday at noon

yesterday, today etc are to be interpreted

English expressions for intervals of time,
- before tea time (i.e. from the beginning of time)
- after 14:00 last month (i.e. till now)
- between last year and last month
- in the last three months (i.e. from then till now)
- 4 months ago (i.e. till now; see englishAgo)
|
|
|
Durations in English that begin with the word "last",
E.g. "last 4 months" is treated as the duration between
4 months ago and now

Intervals in ISO 8601, e.g.,
- 2008-09/2012-08-17T16:30
- 2008-09/P2Y11MT16H30M
- P2Y11MT16H30M/2012-08-17T16:30

Convert a date string into ISO 8601 format (yyyymmdd variant)
assuming local timezone if not specified in the string

Set a calendar to UTC time any eliminate any inconsistencies within
(for example, where the weekday is given as Thursday, but this does not
match what the numerical date would lead one to expect)

An MCalenderTime is an underspecified CalendarTime
It is used for parsing dates. For example, if you want to parse
the date '4 January', it may be useful to underspecify the year
by setting it to Nothing. This uses almost the same fields as
CalendarTime, a notable exception being that we
introduce mctWeek to indicate if a weekday was specified or not

|
|
Trivially convert a CalendarTime to a fully specified
MCalendarTime (note that this sets the mctWeek flag to
False
|
|
|
Returns the first CalendarTime that falls within a MCalendarTime
This is only unsafe in the sense that it plugs in default values
for fields that have not been set, e.g. January for the month
or 0 for the seconds field.
Maybe we should rename it something happier.
