Nitrocid KS provides an API that allows you to perform date and time operations, like rendering them to a string instance, managing time zones, and starting alarms. This feature is found under the Nitrocid.Kernel.Time namespace, as this feature is crucial for the kernel to be able to tell the current date (today) and the current time (now).
The tools let you perform from the simplest operations, such as getting the current date and time, to the most complex operations, such as converting date and time to other formats, such as the Unix time.
The base time/date tools allow you to perform general time and date operations, such as getting remaining time from either the current moment or from the selected moment. These functions allow you to perform this operation easily:
GetRemainingTimeFromNow(): Returns a TimeSpan instance that indicates the remaining time from the current moment to the specified amount of milliseconds.
GetRemainingTimeFrom(): Returns a TimeSpan instance that indicates the remaining time from the specified moment to the specified amount of milliseconds.
Not only these tools are readily available for you to use, but you can also use this class to get the current date and time in both the local time (KernelDateTime) and the UTC time zone (KernelDateTimeUtc).
Nitrocid KS provides a built-in time zone API that allows you to get information about a time zone and convert the time to the equivalent time using the specific time zone. This API is found in the TimeZones class.
One of the functions that the above class implements is GetZoneTimeString() and its sibling functions, GetZoneTimeTimeString() and GetZoneTimeDateString().
The first function returns the full date and time using the specified time zone.
The second function returns the time using the specified time zone.
The third function returns the date using the specified time zone.
In addition to providing the calendar command in the addon, the base Nitrocid API provides some of the calendar management APIs to make access to them easier than before. You can now get the calendar straight from the calendar type or its name using the GetCalendar() function from the CalendarTools class.
Additionally, the time and date renderers can be used with the base calendar class instance obtained from the above function. The following calendars can be used:
Chinese: zh-CN
Gregorian: en-US
Hijri: ar
Japanese: ja-JP
Persian: fa
SaudiHijri: ar-SA
Taiwanese: zh-TW
ThaiBuddhist: th-TH
Variant: Your culture as specified by your kernel configuration
It's important to take note of these:
While the events can be configured to be a yearly event, such as the Nitrocid KS release anniversary, such events have to be created by hand until the event commands are updated.
Although it looks like that you can make your own custom calendar, there are no available methods to register your own calendar. We'll work on it in the next Nitrocid release. For now, use your newly-created instance of your calendar.
Nitrocid API provides date conversion tools that allow you to change how the date and the time are being represented. For instance, you can translate the date and the time to UNIX time and vice versa.
As for the calendars, you can use the GetDateFromCalendar() function, provided that you have a calendar instance from the GetCalendar() function. Also, you can use the GetDateFromCalendarNoCulture() function for calendars with overridden Calendar property.
In addition to the above time tools, there are some of the features that use the date and time feature as an essential recipe for their implementation.
When it comes to alarms, they are useful to alarm you for something at a specified time. This service and its tools can be accessed via the AlarmTools class.
You can start an alarm using the StartAlarm() function that lets you specify your alarm ID, your alarm name, and your alarm interval in seconds.
Additionally, you can stop an alarm before it's up using a function defined below:
The renderers are essential if you want to get the text form of either the current date and time or the selected date and time. This is to simplify the functions that are used to do the same thing, but in the more coherent form to be able to use it like never before. The following classes are available for you to use in your mods:
TimeDateRenderers: This class provides general time and date renderers that use your local time zone to return a text indicating either the current time and date or the selected time and date. You can optionally specify a target date, a target culture/calendar, and a target format type.
TimeDateRenderersUtc: This class provides general time and date renderers that use UTC to return a text indicating either the current time and date or the selected time and date. You can optionally specify a target date, a target culture/calendar, and a target format type.
TimeDateMiscRenderers: This class provides miscellaneous time and date renderers, including getting a string instance of the remaining time and printing the current date and time to the console.
Nitrocid KS provides an option to show the date and time in the upper right corner. If you've enabled this option, you'll be able to see the current date and time there. To enable or to disable this feature, you must open the kernel settings application using the settings command, then Miscellaneous settings > Show Time/Date on Upper Right Corner. Once enabled, you should be able to see the current date and time in the corner as shown in the above picture.
For Linux systems, a check for /usr/share/zoneinfo is performed, and if it doesn't exist, you'll be prompted to install tzdata from your Linux distribution's repository. See the for more information about how to install this package to your system.
In some renderers, you can use the custom date and time formats, as long as they specify a valid syntax to print the date and the time. You can refer to for more information about how to write a valid date and time format.
