Aliases

DosFileTime alias DosFileTime = uint: Type representing the DOS file date/time format.
d_time alias d_time = long: d_time is a signed arithmetic type giving the time elapsed since January 1, 1970. Negative values are for dates preceding 1970. The time unit used is Ticks. Ticks are milliseconds or smaller intervals.
toString deprecated alias toString = UTCtoString: Alias for UTCtoString (deprecated).

Functions

UTCtoLocalTime d_time UTCtoLocalTime(d_time t): Convert from UTC to local time.
UTCtoString string UTCtoString(d_time time): Converts UTC time into a text string of the form: "Www Mmm dd hh:mm:ss GMT+-TZ yyyy". For example, "Tue Apr 02 02:04:57 GMT-0800 1996". If time is invalid, i.e. is d_time_nan, the string "Invalid date" is returned.
benchmark ulong[] benchmark(uint times, ulong[] result): Benchmarks code for speed assessment and comparison.
dateFromNthWeekdayOfMonth int dateFromNthWeekdayOfMonth(int year, int month, int weekday, int n): Determine the date in the month, 1..31, of the nth weekday.
dateFromTime int dateFromTime(d_time t): Compute which day in a month a d_time t is.
dayFromYear int dayFromYear(int year): Calculates the number of days elapsed since 1 January 1970 until 1 January of the given year.
daysInMonth int daysInMonth(int year, int month): Determine the number of days in a month, 1..31.
daysInYear uint daysInYear(uint year): Calculates the number of days that exists in a year.
getUTCtime d_time getUTCtime(): Get current UTC time.
getUTCtime d_time getUTCtime(): Get current UTC time.
hourFromTime int hourFromTime(d_time time): Calculates the hour from time.
inLeapYear bool inLeapYear(d_time t): Determines if d_time t is a leap year.
localTimetoUTC d_time localTimetoUTC(d_time t): Convert from local time to UTC.
minFromTime int minFromTime(d_time time): Calculates the minute from time.
monthFromTime int monthFromTime(d_time t): Calculates the month from the d_time t.
msFromTime int msFromTime(d_time time): Calculates the milisecond from time.
parse d_time parse(string s): Parses s as a textual date string, and returns it as a d_time. If the string is not a valid date, d_time_nan is returned.
secFromTime int secFromTime(d_time time): Calculates the second from time.
toDateString string toDateString(d_time time): Converts the date portion of time into a text string of the form: "Www Mmm dd yyyy", for example, "Tue Apr 02 1996". If time is invalid, "Invalid date" is returned.
toDosFileTime DosFileTime toDosFileTime(d_time t): Convert from d_time to DOS file date/time.
toDtime d_time toDtime(DosFileTime time): Convert from DOS file date/time to d_time.
toISO8601YearWeek void toISO8601YearWeek(d_time t, int year, int week): Compute year and week [1..53] from t. The ISO 8601 week 1 is the first week of the year that includes January 4. Monday is the first day of the week. References: ISO 8601 (Wikipedia)
toTimeString string toTimeString(d_time time): Converts the time portion of t into a text string of the form: "hh:mm:ss GMT+-TZ", for example, "02:04:57 GMT-0800". If t is invalid, "Invalid date" is returned. The input must be in UTC, and the output is in local time.
toUTCString string toUTCString(d_time t): Converts t into a text string of the form: "Www, dd Mmm yyyy hh:mm:ss UTC". If t is invalid, "Invalid date" is returned.
weekDay int weekDay(d_time t): Compute which day of the week a d_time t is.
yearFromTime int yearFromTime(d_time t): Calculates the year from the d_time t.

Structs

Date struct Date: Time broken down into its components.

Variables

d_time_nan enum d_time d_time_nan;: A value for d_time that does not represent a valid time.
