Class std.datetime.LocalTime
A TimeZone which represents the current local time zone on
the system running your program.
This uses the underlying C calls to adjust the time rather than using
specific D code based off of system settings to calculate the time such as
PosixTimeZone and WindowsTimeZone do. That also means that it will
use whatever the current time zone is on the system, even if the system's
time zone changes while the program is running.

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 in effect in this
time zone at the given point in time.
|
opCall
|
LocalTime is a singleton class. LocalTime returns its only
instance.
|
tzToUTC
|
Returns std time using the standard C function calls on Posix systems
and the standard Windows system calls on Windows systems to adjust the
time to UTC from the appropriate time zone.
|
utcToTZ
|
Returns hnsecs in the local time zone using the standard C function calls on Posix systems and the standard Windows system calls on Windows systems to adjust the time to the appropriate time zone from std time. |
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.
|
factory
|
Create instance of class specified by the fully qualified name
classname.
The class must either have no constructors or have
a default constructor.
|
getInstalledTZNames
|
Returns a list of the names of the time zones installed on the system. |
getTimeZone
|
Returns a .TimeZone, TimeZone with the give name per the TZ Database.
|
opCmp
|
Compare with another Object obj.
|
opEquals
|
Returns !=0 if this object does have the same contents as obj.
|
toHash
|
Compute hash function for Object.
|
toString
|
Convert Object to a human readable string.
|
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.
