I saw something similar on here but not quite the same.
I need a java class wall clock time.
The iso 8601 calendar system is the modern civil calendar system used today in most of the world.
Java time clock system zoneid zone method is a static method of clock class which returns a clock that returns the current instant of the clock using best available system clock with zoneid of the returned clock is set to the zoneid passed.
Instances of this class are used to find the current instant which can be interpreted using the stored time zone to find the current date and time.
Anyways the task is to create a java clock class and access use it from a driver.
5 there should be constructors that allow the user to set the time as desired and a default constructor that sets the time at 00 00 00 high midnight 6.
As such a clock can be used instead of system currenttimemillis and timezone getdefault.
The current date and time depend on the time zone and for globalized applications a time provider is necessary to ensure that the date and time are created with the correct time zone.
Instead it is a description of the local time as seen on a wall clock.
Following is the declaration for java io clock class public abstract class clock extends object class constructors.
However the result may and will be inaccurate as system currenttimemillis measures wall clock time.
Java clock class usage is optional because most of the date api classes has now method.
The clock class was added in java 8 and provides access to an instant in time using the best available system clock and to be used as a time provider which can be effectively stubbed for testing purposes.
Use of a clock is.
On top of that there are other stipulations.
Time elapsed is the difference between these two values.
It s main purpose is to allow alternate clocks to be plugged in as and when required.
It cannot represent an instant on the time line without additional information such as an offset or time zone.
Wall clock time may change for many reasons e g.
The java time clock class provides access to the current instant date and time using a time zone.
A clock providing access to the current instant date and time using a time zone.
Changing the system time can affect the results or a leap second will disrupt the result.
This class does not store or represent a date or time zone.
This method can use system currenttimemillis or other higher resolution clock if the clock is available to use.
