Properties
Name | Type | Description |
---|---|---|
dstName [get]
|
string | Typically, the abbreviation (generally 3 or 4 letters) for the time zone when DST is in effect (e.g. PDT). It is not necessarily unique. |
hasDST [get]
|
bool | Whether this time zone has Daylight Savings Time at any point in time.
Note that for some time zone types it may not have DST for current dates
but will still return true for hasDST because the time zone did at
some point have DST.
|
name [get]
|
string | The name of the time zone. Exactly how the time zone name is formatted
depends on the derived class. In the case of PosixTimeZone , it's
the TZ Database name, whereas with WindowsTimeZone , it's the
name that Windows chose to give the registry key for that time zone
(typically the name that they give stdTime if the OS is in
English). For other time zone types, what it is depends on how they're
implemented.

stdName [get]

Methods
Name | Description |
---|---|
dstInEffect
|
Takes the number of hnsecs (100 ns) since midnight, January 1st, 1 A.D. in UTC time (i.e. std time) and returns whether DST is effect in this time zone at the given point in time. |
tzToUTC
|
Takes the number of hnsecs (100 ns) since midnight, January 1st, 1 A.D. in this time zone's time and converts it to UTC (i.e. std time). |
utcOffsetAt
|
Returns what the offset from UTC is at the given std time. It includes the DST offset in effect at that time (if any). |
utcToTZ
|
Takes the number of hnsecs (100 ns) since midnight, January 1st, 1 A.D. in UTC time (i.e. std time) and converts it to this time zone's time. |
factory
|
Create instance of class specified by the fully qualified name classname. The class must either have no constructors or have a default constructor. |
opCmp
|
Compare with another Object obj. |
opEquals
|
Test whether this is equal to o .
The default implementation only compares by identity (using the is operator).
Generally, overrides for opEquals should attempt to compare objects by their contents.
|
toHash
|
Compute hash function for Object. |
toString
|
Convert Object to a human readable string. |
