Overview ¶
The Time singleton allows converting time between various formats and also getting time information from the system.
This class conforms with as many of the ISO 8601 standards as possible. All dates follow the Proleptic Gregorian calendar. As such, the day before 1582-10-15 is 1582-10-14, not 1582-10-04. The year before 1 AD (aka 1 BC) is number 0, with the year before that (2 BC) being -1, etc.
Conversion methods assume "the same timezone", and do not handle timezone conversions or DST automatically. Leap seconds are also not handled, they must be done manually if desired. Suffixes such as "Z" are not handled, you need to strip them away manually.
When getting time information from the system, the time can either be in the local timezone or UTC depending on the utc parameter. However, the GetUnixTimeFromSystem method always uses UTC as it returns the seconds passed since the Unix epoch.
Important: The _from_system methods use the system clock that the user can manually set. Never use this method for precise time calculation since its results are subject to automatic adjustments by the user or the operating system. Always use GetTicksUsec or GetTicksMsec for precise time calculation instead, since they are guaranteed to be monotonic (i.e. never decrease).

Functions ¶
func Advanced ¶
func Advanced() class
Advanced exposes a 1:1 low-level instance of the class, undocumented, for those who know what they are doing.
func GetDateStringFromSystem ¶
Returns the current date as an ISO 8601 date string (YYYY-MM-DD).
The returned values are in the system's local time when 'utc' is false, otherwise they are in UTC.
func GetDateStringFromSystemOptions ¶
Returns the current date as an ISO 8601 date string (YYYY-MM-DD).
The returned values are in the system's local time when 'utc' is false, otherwise they are in UTC.
func GetDateStringFromUnixTime ¶
Converts the given Unix timestamp to an ISO 8601 date string (YYYY-MM-DD).
func GetDatetimeStringFromDatetimeDict ¶
Converts the given dictionary of keys to an ISO 8601 date and time string (YYYY-MM-DDTHH:MM:SS).
The given dictionary can be populated with the following keys: year, month, day, hour, minute, and second. Any other entries (including dst) are ignored.
If the dictionary is empty, 0 is returned. If some keys are omitted, they default to the equivalent values for the Unix epoch timestamp 0 (1970-01-01 at 00:00:00).
If 'use_space' is true, the date and time bits are separated by an empty space character instead of the letter T.
func GetDatetimeStringFromSystem ¶
Returns the current date and time as an ISO 8601 date and time string (YYYY-MM-DDTHH:MM:SS).
The returned values are in the system's local time when 'utc' is false, otherwise they are in UTC.
If 'use_space' is true, the date and time bits are separated by an empty space character instead of the letter T.
func GetDatetimeStringFromSystemOptions ¶
Returns the current date and time as an ISO 8601 date and time string (YYYY-MM-DDTHH:MM:SS).
The returned values are in the system's local time when 'utc' is false, otherwise they are in UTC.
If 'use_space' is true, the date and time bits are separated by an empty space character instead of the letter T.
func GetDatetimeStringFromUnixTime ¶
Converts the given Unix timestamp to an ISO 8601 date and time string (YYYY-MM-DDTHH:MM:SS).
If 'use_space' is true, the date and time bits are separated by an empty space character instead of the letter T.
func GetDatetimeStringFromUnixTimeOptions ¶
Converts the given Unix timestamp to an ISO 8601 date and time string (YYYY-MM-DDTHH:MM:SS).
If 'use_space' is true, the date and time bits are separated by an empty space character instead of the letter T.
func GetOffsetStringFromOffsetMinutes ¶
Converts the given timezone offset in minutes to a timezone offset string. For example, -480 returns "-08:00", 345 returns "+05:45", and 0 returns "+00:00".
func GetTicksMsec ¶
func GetTicksMsec() int
Returns the amount of time passed in milliseconds since the engine started.
Will always be positive or 0 and uses a 64-bit value (it will wrap after roughly 500 million years).
func GetTicksUsec ¶
func GetTicksUsec() int
Returns the amount of time passed in microseconds since the engine started.
Will always be positive or 0 and uses a 64-bit value (it will wrap after roughly half a million years).
func GetTimeStringFromSystem ¶
Returns the current time as an ISO 8601 time string (HH:MM:SS).
The returned values are in the system's local time when 'utc' is false, otherwise they are in UTC.
func GetTimeStringFromSystemOptions ¶
Returns the current time as an ISO 8601 time string (HH:MM:SS).
The returned values are in the system's local time when 'utc' is false, otherwise they are in UTC.
func GetTimeStringFromUnixTime ¶
Converts the given Unix timestamp to an ISO 8601 time string (HH:MM:SS).
func GetUnixTimeFromDatetimeDict ¶
Converts a dictionary of time values to a Unix timestamp.
The given dictionary can be populated with the following keys: year, month, day, hour, minute, and second. Any other entries (including dst) are ignored.
If the dictionary is empty, 0 is returned. If some keys are omitted, they default to the equivalent values for the Unix epoch timestamp 0 (1970-01-01 at 00:00:00).
You can pass the output from GetDatetimeDictFromUnixTime directly into this function and get the same as what was put in.
Note: Unix timestamps are often in UTC. This method does not do any timezone conversion, so the timestamp will be in the same timezone as the given datetime dictionary.
func GetUnixTimeFromDatetimeString ¶
Converts the given ISO 8601 date and/or time string to a Unix timestamp. The string can contain a date only, a time only, or both.
Note: Unix timestamps are often in UTC. This method does not do any timezone conversion, so the timestamp will be in the same timezone as the given datetime string.
Note: Any decimal fraction in the time string will be ignored silently.
func GetUnixTimeFromSystem ¶
Returns the current Unix timestamp in seconds based on the system time in UTC. This method is implemented by the operating system and always returns the time in UTC. The Unix timestamp is the number of seconds passed since 1970-01-01 at 00:00:00, the Unix epoch.
Note: Unlike other methods that use integer timestamps, this method returns the timestamp as a [Float.X] for sub-second precision.
Types ¶
type Date ¶
type Date struct { Year int `gd:"year"` Month int `gd:"month"` Day int `gd:"day"` Weekday int `gd:"weekday"` Hour int `gd:"hour"` Minute int `gd:"minute"` Second int `gd:"second"` }
func GetDatetimeDictFromDatetimeString ¶
Converts the given ISO 8601 date and time string (YYYY-MM-DDTHH:MM:SS) to a dictionary of keys: year, month, day, weekday, hour, minute, and second.
If 'weekday' is false, then the weekday entry is excluded (the calculation is relatively expensive).
Note: Any decimal fraction in the time string will be ignored silently.
func GetDatetimeDictFromSystem ¶
Returns the current date as a dictionary of keys: year, month, day, weekday, hour, minute, second, and dst (Daylight Savings Time).
func GetDatetimeDictFromSystemOptions ¶
Returns the current date as a dictionary of keys: year, month, day, weekday, hour, minute, second, and dst (Daylight Savings Time).
func GetDatetimeDictFromUnixTime ¶
Converts the given Unix timestamp to a dictionary of keys: year, month, day, weekday, hour, minute, and second.
The returned Dictionary's values will be the same as the GetDatetimeDictFromSystem if the Unix timestamp is the current time, with the exception of Daylight Savings Time as it cannot be determined from the epoch.
type DateOnly ¶
type DateOnly struct { Year int `gd:"year"` Month int `gd:"month"` Day int `gd:"day"` Weekday int `gd:"weekday"` }
func GetDateDictFromSystem ¶
Returns the current date as a dictionary of keys: year, month, day, and weekday.
