The timezone is UTC. As a -general philosophical point, dates written out persisetntly should generally -be in UTC, so this function should generally be used to get dates. - -Returns: An instant representing the current time in the UTC timezone. - - const now : (tz : byte[:] -> instant) - -Creates an instant representing the current time. The timezone is the local -time. This is useful for displaying dates and times to the user. - -Returns: An instant representing the current time in the local timezone. - - const tozone : (d : instant, zone : byte[:] -> instant) - -Takes an instant and converts it to a new timezone. This takes the instants by -value, and therefore, does not mutate any of its arguments. - -Returns: An instant representing provided time in the requested timezone. - - const mkdate : (y : int, m : int, day : int, zone : byte[:] -> instant) - -Creates a date with the given year, month, and day in the given timezone. The -time is set to 0:00:00 - -Returns: A date representing the given ymd - - const mkdatetime : (year : int, mon : int, day : int, \ - h : int, m : int, s : int, zone : byte[:] -> instant) - -Creates a date and time pair with the given year, month, day, at the time -h, m, s, in the provided timezone. The microseconds are zeroed. - -Returns: A date representing the given ymd:hms - - const mkinstant : (tm : std.time, zone : byte[:] -> instant) - -Creates an instant from a time type. This time can be derived from the -standard library, or computed from any other source. The time is in -microseconds since the Unix epoch (Jan 1 1970, 0:00, UTC). - -Returns: An instant representing a std.time in the requested timezone - -Timezones ---------- - - const localoff : (tm : std.time -> duration) - -Gets the local timezone offset for a time. Note that timezones can change due -daylight savings, politics, and other similar factors, so a timezone offset -needs to be associated with a specific instant. - -Returns: a duration representing the local timezone offset. - - const tzoff : (tzname : byte[:], tm : std.time -> duration) - -Gets the timezone offset for a time and timezone pair. Note that timezones can -change due daylight savings, politics, and other similar factors, so a -timezone offset needs to be associated with a specific instant. - -Returns: a duration representing the requested timezone offset. - - const isleap : (d : instant -> bool) - -Returns: whether a specific instant is within a leap year or not. - -Manipulation ------------- - - const add : (d : instant, dt : duration -> instant) - const sub : (d : instant, dt : duration -> instant) - -Adds or subtracts a duration from a date. A duration is an absolute length of -time, and is not adjusted for calendar shifts around DST and similar events. - -Returns: an instant representing the adjusted time. - - const addperiod : (d : instant, dt : period -> instant) - const subperiod : (d : instant, dt : period -> instant) - -Adds or subtracts a period from a date. A period is a humanized length of -time, and is adjusted for calendar shifts around DST and similar events. - -Returns: an instant representing the adjusted time. - - const duration : (a : instant, b : instant -> duration) - -Returns: the duration representing the difference between the two provided -instants. - - |
