struct Time::Location::Zone
Overview
A Zone
represents a time zone offset in effect in a specific Location
.
Some zones have a #name
or abbreviation (such as PDT
, CEST
).
For an unnamed zone the formatted offset should be used as name.
Defined in:
time/location.crConstant Summary
-
UTC =
new("UTC", 0, false)
-
This is the
UTC
time zone with offset+00:00
.It is the only zone offset used in
Time::Location::UTC
.
Constructors
-
.new(name : String?, offset : Int32, dst : Bool)
Creates a new
Zone
named name with offset from UTC in seconds.
Instance Method Summary
-
#dst? : Bool
Returns
true
if this zone offset is daylight savings time. -
#format(io : IO, with_colon = true, with_seconds = :auto)
Prints
#offset
to io in the format+HH:mm:ss
. -
#format(with_colon = true, with_seconds = :auto)
Returns the
#offset
formatted as+HH:mm:ss
. -
#inspect(io : IO) : Nil
Prints this
Zone
to io. -
#name : String
Returns the name of the zone.
-
#offset : Int32
Returns the offset from UTC in seconds.

Constructor Detail
Creates a new Zone
named name with offset from UTC in seconds.
The parameter dst is used to declare this zone as daylight savings time.
If #name
is nil
, the formatted #offset
will be used as #name
(see
#format
).
Raises InvalidTimezoneOffsetError
if seconds is outside the supported
value range -86_400..86_400
seconds (-24:00
to +24:00
).
Instance Method Detail
Prints #offset
to io in the format +HH:mm:ss
.
When with_colon is false
, the format is +HHmmss
.
When with_seconds is false
, seconds are omitted; when :auto
, seconds
are omitted if 0
.
Returns the #offset
formatted as +HH:mm:ss
.
When with_colon is false
, the format is +HHmmss
.
When with_seconds is false
, seconds are omitted; when :auto
, seconds
are omitted if 0
.
