Influences time->value and value->time functions as well as all ‘?’ functions. Valid values: :gregorian (default) :julian :islamic :hebrew

This variable is supposed to be used through with-time-configuration macro. Specify function that calculates if given day-context is holiday or not. Look @ “day-context” Returns boolean

Variable that is used in function get-dst-offset. ->local, <-local and day? funcitons are affected when changing value of this variable. I.E. (binding offset (hours -2) …) would make all computations in that offset from UTC.

Variable that is used in function get-dst-offset. ->local, <-local and day? funcitons are affected when changing value of this variable. I.E. (binding timezone :hr …) would make all computations in that time zone (offset).

This variable can be used to customize weekend? function to return true or false for day-context. Function should accept one argument that is supposed to be day 1-7 and return true or false.

Returns Date object that was after some time value

Returns Date object that was before some time value

Returns sequence of days for given value that are contained in that frame-type. List is consisted of keys:

:value :day :week :month :day-in-month :weekend? :holiday? :first-day-in-month? :last-day-in-month?

for Gregorian calendar. Frame types can be extened by implementing different calendar-frame functions. Timing supports calendar-frames for: * year * month * week

Computes interval statistics based on start Date and end Date * start * end * start-context * end-context * years * months * days * hours * minutes * seconds * holidays * weekends

Function turns map of time units to value

Constructs new Date object

Returns number of milliseconds from UNIX epoch

Returns value of Date instance in seconds. Value is localized to offset

86400000

Returns day context with DST-accurate hour value. Use this instead of day-time-context when you need accurate :hour during DST transitions.

Returns which day (Gregorian) in month input value belongs to. For example for date 15.02.2015 it will return number 15

Returns day in year period (1 - 366)

Returns day context for given value in Gregorian calendar.

Returnes hash-map with keys: :value :millisecond :second :hour :day :week :month :year :day-in-month :weekend? :holiday? :first-day-in-month? :last-day-in-month?

Note: For DST-accurate hour values, use day-context instead.

Returns which day in week does input value belongs to. For example for date 15.02.2015 it will return number 7

Function returns value of n days as number.

Returns value of first day in current month

Returns true if value in seconds belongs to first day in month.

Returns DST offset for UTC input value

3600000

Returns which hour in day does input value belongs to. For example for date 15.02.2015 it will return number 0

Function returns value of n hours as number.

Returns period of time value in milliseconds between start and end. Input values are supposed to be Date.

Given sequence of timestamps (Date) values returns period values between each timestamp value in milliseconds

Returns value of last day in current month

Returns true if value in seconds belongs to last day in month.

1.0E-3

Function calculates value of midnight for given value. For example if some date value is inputed it will round-number to the begining of that day.

1

Returns which millisecond in day does input value belongs to. For example for date 15.02.2015 it will return number 0

Function returns value of n seconds as number.

60000

Returns which hour in day does input value belongs to. For example for date 15.02.2015 it will return number 0

Function returns value of n minutes as number.

Returns which month does input value belongs to. For example for date 15.02.2015 it will return number 2

1.0E-6

Returns number of seconds of all input arguments added together

Returns duration of for input value in form of map with keys:

:weeks :days :hours :minutes :seconds :milliseconds

Function returns round number that is devidable by target-number. Rounding strategy can be specified in round-how? options:

:floor :ceil :up :down

Rounding number strategy is symetric to 0. This means that :ceil will round negative numbers to lower target-number. I.E (round-number -9.5 1 :ceil) would return -10. Rounding happens in absolute domain and sign is inserted afterwards.

Negative target-numbers are not supported. Can’t reason about that yet. Maybe for imaginary numbers?

1000

Returns which second in day does input value belongs to. For example for date 15.02.2015 it will return number 0

Function returns value of n seconds as number.

Teleports value to different timezone.

bindings => name (time->value x) …

Similar to let or binding. Casts all bound symbol values with function time->value. Then evaluates body.

Computes value for given arguments depending with respect to calendar binding

Returns Date instance for value in seconds for current. Function first transforms value to local timezone value.

Casts value to UTC value of Date object

Returns value relative to current month

Returns value relative to current year

604800000

Returns which week in year does input value belongs to. For example for date 15.02.2015 it will return number 6

Returns true if value in seconds belongs to weekend-days

Function returns value of n weeks as number.

Utility macro to put context frame on computation scope. Specify:

:holiday? - (fn day-context true | false) :timezone - timezone-name :weekend-days - (fn number true | false) :calendar - :gregorian, :julian, :islamic, :hebrew

WARNING: Lazy sequences may be realized outside this binding scope. Use (doall …) or (vec …) to force evaluation within the binding:

(with-time-configuration {:timezone “UTC”} (vec (map day-time-context values))) ; Force evaluation here

Convenience macro for UTC timezone context. Equivalent to: (with-time-configuration {:timezone “UTC” :offset 0} …)

For given value year? returns year that value belogs to.
