Implement Enso Time Library (#1171)

Browse Source 
Add `Base.Time` module. The module wraps `java.time`
data types and provides utility Enso methods to work
with them.

type Date
## `Date` represents a date, often viewed as year-month-day. For example,
the value "2nd October 2007" can be stored in a `Date`.
This class does not store or represent a time or timezone. Instead, it
is a description of the date, as used for birthdays. It cannot represent
an instant on the time-line without additional information such as an
offset or timezone.
type Date internal_local_date
## Get the year field.
year : Integer
year = this . internal_local_date . getYear []
## Get the month of year field, as a number from 1 to 12.
month : Integer
month = this . internal_local_date . getMonthValue []
## Get the day of month field.
day : Integer
day = this . internal_local_date . getDayOfMonth []
## Combine this date with time of day to create a point in time.
> Example
Convert this date to midnight UTC time.
Day.new 2020 2 3 . to_time Time_Of_Day.new Zone.utc
to_time : Time_Of_Day -> Zone -> Time
to_time daytime (zone = Zone.system) = Time.time (this . internal_local_date . atTime [daytime.internal_local_time] . atZone [zone.internal_zone_id])
## Add specified amount of time to this instant.
> Example
Add 6 months to a local date.
Date.new 2020 + 6.months
+ : Duration -> Date
+ amount = if amount.is_time then Error.throw (Time.Time_Error "Date does not support time intervals") else Date (this . internal_local_date . plus [amount.interval_period])
## Subtract specified amount of time to this instant.
> Example
Subtract 7 days from a local date.
Date.new 2020 - 7.days
- : Duration -> Date
- amount = if amount.is_time then Error.throw (Time.Time_Error "Date does not support time intervals") else Date (this . internal_local_date . minus [amount.interval_period])
## Format this date using the default formatter.
to_text : Text
to_text = Time_Utils.default_date_formatter [] . format [this.internal_local_date]
## Format this date using formatter text.
Patterns are based on a simple sequence of letters and symbols. For
example, "d MMM yyyy" will format "2011-12-03" as "3 Dec 2011".
For the list of accepted symbols in pattern refer to
`Base.Time.Time.format` doc.
> Example
Format "2020-06-02" as "2 June 2020"
Date.new 2020 6 2 . format "d MMMM yyyy"
> Example
Format "2020-06-02" as "2 June 20"
Date.new 2020 6 2 . format "d MMMM yy"
> Example
Format "2020-06-02" as "Tuesday, 02 June 2020"
Date.new 2020 6 2 . format "EEEE, dd MMMM yyyy"
> Example
Format "2020-06-02" as "Tue Jun 2"
Date.new 2020 6 2 . format "EEE MMM d"
> Example
Format "2020-06-02" as "2020AD"
Date.new 2020 6 2 . format "yyyyGG"
format : Text -> Text
format pattern = DateTimeFormatter.ofPattern [pattern] . format [this.internal_local_date]
## Obtains an instance of `Date` from a text, such as "2007-12-03".
The text must represent a valid date and is parsed using the ISO-8601
extended local date format. The format consists of:
- Four digits or more for the year. Years in the range 0000 to 9999
will be pre-padded by zero to ensure four digits. Years outside
that range will have a prefixed positive or negative symbol.
- A dash
- Two digits for the month-of-year. This is pre-padded by zero to ensure two
digits.
- A dash
- Two digits for the day-of-month. This is pre-padded by zero to ensure two
digits.
> Example
Parse the date of 23rd December 2020.
Date.parse "2020-12-23"
> Example
Recover from the parse error.
Date.parse "my birthday" . catch <| case _ of
Time.Error _ -> Date.new 2000 1 1
parse : Text -> Date
parse text =
Panic.recover (Date (LocalDate.parse [text])) . catch <| case _ of
Polyglot_Error err -> Error.throw (Time.Time_Error (err.getMessage []))
x -> x
## Obtains an instance of `Date` from a text using custom format.
For the list of accepted symbols in pattern refer to
`Base.Time.Time.format` doc.
> Example
Parse "1999-1-1" as Date.
Date.parse_format "1999-1-1" "yyyy-M-d"
> Example
Recover from the parse error.
date = Date.parse "1999-1-1" "yyyy-MM-dd"
date.catch <| case _ of
Time.Error msg -> Date.new 2000 1 1
parse_format : Text -> Text -> Date
parse_format text pattern =
format = DateTimeFormatter.ofPattern [pattern]
Panic.recover (Date (LocalDate.parse [text, format])) . catch <| case _ of
Polyglot_Error err -> Error.throw (Time.Time_Error (err.getMessage []))
x -> x
## Obtains the current date from the system clock in the system timezone.
now : Date
now = Date (LocalDate.now [])
## Alias for `now`.
today : Date
today = here.now
## Obtains an instance of `Date` from a year, month and day.
- month - the month-of-year to represent, from 1 (January) to 12 (December)
- day - the day-of-month to represent, from 1 to 31 and must be valid for the
year and month
> Example
Create a new local date at Unix epoch.
Date.new 1970
> Example
Get the local date of 5th August 1986.
Date.new 1986 8 5
new : Integer -> Integer -> Integer -> Date

## A date-time with a timezone in the ISO-8601 calendar system, such as
"2007-12-03T10:15:30+01:00 Europe/Paris".
Time is a representation of a date-time with a timezone. This class
stores all date and time fields, to a precision of nanoseconds, and a
timezone, with a zone offset used to handle ambiguous local
date-times.
For example, the value "2nd October 2007 at 13:45.30.123456789 +02:00 in
the Europe/Paris timezone" can be stored as `Time`.

## Obtains an instance of `Time` from a text such as
"2007-12-03T10:15:30+01:00 Europe/Paris".
The text must represent a valid date-time and is parsed using the ISO-8601
extended offset date-time format to add the timezone. The section in square
brackets is not part of the ISO-8601 standard. The format consists of:
- The ISO offset date time.
- If the zone ID is not available or is a zone offset then the format is
complete.
- An open square bracket '['.
- The zone ID. This is not part of the ISO-8601 standard. Parsing is case
sensitive.
- A close square bracket ']'.
> Example
Parse UTC time.
Time.parse "2020-10-01T04:11:12Z"
> Example
Parse UTC-04:00 time.
Time.parse "2020-10-01T04:11:12-04:00"
> Example
Parse UTC-04:00 time specifying New York timezone.
Time.parse "2020-10-01T04:11:12-04:00[America/New_York]"
> Example
Parse UTC-04:00 time with nanoseconds.
Time.parse "2020-10-01T04:11:12.177528-04:00"

to_text = Time_Utils.default_time_of_day_formatter [] . format [this.internal_local_time]
## Format this time of day using formatter text.
Patterns are based on a simple sequence of letters and symbols. For
example, "HH-mm-ss.SSS" will format "16:21:10" as "16-21-10.323".
For the list of accepted symbols in pattern refer to
`Base.Time.Time.format` doc.
> Example
Format "16:21:10" as "16:21:00.1234"
Time_Of_Day.new 16 21 10 . format "HH:mm:ss.SSSS"
> Example
Format "16:21:10" as "16:21:00.123456789"
Time_Of_Day.new 16 21 10 . format "HH:mm:ss.n"
> Example
Format "16:21:10" as "4:21pm"
Time_Of_Day.new 16 21 10 . format "h:mma"
> Example
Format "16:21:10" as "04:21:10pm"
Time_Of_Day.new 16 21 10 . format "hh:mm:ssa"
> Example
Format "16:21:10" as "hour:4"
Time_Of_Day.new 16 21 10 . format "'hour:'h"
format : Text -> Text
format pattern = DateTimeFormatter.ofPattern [pattern] . format [this.internal_local_time]
## Obtains an instance of `Time_Of_Day` from a text such as "10:15".
The text must represent a valid time and is parsed using the ISO-8601
extended local time format. The format consists of:
- Two digits for the hour-of-day. This is pre-padded by zero to ensure two
digits.
- A colon
- Two digits for the minute-of-hour. This is pre-padded by zero to ensure two
digits.
- If the second-of-minute is not available then the format is complete.
- A colon
- Two digits for the second-of-minute. This is pre-padded by zero to ensure
two digits.
- If the nano-of-second is zero or not available then the format is complete.
- A decimal point
- One to nine digits for the nano-of-second. As many digits will be output as
required.
> Example
Get the time 15:05:30.
Time_Of_Day.parse "15:05:30"

Recover from the parse error.

## Obtains an instance of Time_Of_Day from a text using custom format.
For the list of accepted symbols in pattern refer to

> Example
Parse "04:30:20" as Time_Of_Day.
Date.parse_format "04:30:20" "HH:mm:ss"

## Obtains the current time from the system clock in the default time-zone.
now : Time_Of_Day
now = Time_Of_Day (LocalTime.now [])
## Obtains an instance of `Time_Of_Day` from an hour, minute, second
and nanosecond.
- hour - the hour-of-day to represent, from 0 to 23
- minute - the minute-of-hour to represent, from 0 to 59
- second - the second-of-minute to represent, from 0 to 59
- nanosecond - the nano-of-second to represent, from 0 to 999,999,999
> Example
Create a new local time at Unix epoch.
Time_Of_Day.new
> Example
Get the local time at 9:30.
Time_Of_Day.new 9 30
new : Integer -> Integer -> Integer -> Integer -> Time_Of_Day
