func BuiltinDurationBetween ¶

func BuiltinDurationBetween(env *lisp.LEnv, args *lisp.LVal) *lisp.LVal

func BuiltinDurationMS ¶

func BuiltinDurationMS(env *lisp.LEnv, args *lisp.LVal) *lisp.LVal

BuiltinDuriationNS returns a float equal to the the number of nanoseconds in the given duration.

func BuiltinDurationNS ¶

func BuiltinDurationNS(env *lisp.LEnv, args *lisp.LVal) *lisp.LVal

BulitinDuriationNS returns an integer equal to the the number of nanoseconds in the given duration.

func BuiltinDurationSeconds ¶

func BuiltinDurationSeconds(env *lisp.LEnv, args *lisp.LVal) *lisp.LVal

BulitinDurationSecods returns a float equal to the the number of seconds in the given duration.

func BuiltinFormatRFC3339 ¶

func BuiltinFormatRFC3339(env *lisp.LEnv, args *lisp.LVal) *lisp.LVal

func BuiltinFormatRFC3339Nano ¶

func BuiltinFormatRFC3339Nano(env *lisp.LEnv, args *lisp.LVal) *lisp.LVal

func BuiltinParseDuration ¶

func BuiltinParseDuration(env *lisp.LEnv, args *lisp.LVal) *lisp.LVal

func BuiltinParseRFC3339 ¶

func BuiltinParseRFC3339(env *lisp.LEnv, args *lisp.LVal) *lisp.LVal

func BuiltinParseRFC3339Nano ¶

func BuiltinParseRFC3339Nano(env *lisp.LEnv, args *lisp.LVal) *lisp.LVal

func BuiltinSleep ¶

func BuiltinSleep(env *lisp.LEnv, args *lisp.LVal) *lisp.LVal

BuiltinSleep sleeps for the given duration before returning.

LoadPackage does not register it: the time package offers no builtin whose result depends on goroutine timing (#757). It stays exported for hosts that register a sleep in their own package, with formals (time-duration &key max).

The sleep is bounded by the evaluation's context (see LEnv.Context): it wakes early if the context is cancelled, and never sleeps past the context's deadline. See sleepContext for the full rationale.

func BuiltinTimeAdd ¶

func BuiltinTimeAdd(env *lisp.LEnv, args *lisp.LVal) *lisp.LVal

func BuiltinTimeEq ¶

func BuiltinTimeEq(env *lisp.LEnv, args *lisp.LVal) *lisp.LVal

func BuiltinTimeGT ¶

func BuiltinTimeGT(env *lisp.LEnv, args *lisp.LVal) *lisp.LVal

func BuiltinTimeLT ¶

func BuiltinTimeLT(env *lisp.LEnv, args *lisp.LVal) *lisp.LVal

func Duration ¶

func Duration(d time.Duration) *lisp.LVal

Duration returns an LVal representing duration d.

func Get ¶

func Get(v *lisp.LVal) (time.Time, bool)

Get returns a Go time.Time with an independent timezone object. Mutating its Location cannot change v or another export. The timezone's value is preserved, not its pointer identity. Nil and non-native values return the zero time and false. Raw host time.Time natives remain supported, but are not automatically approved for template sharing.

func GetDuration ¶

func GetDuration(v *lisp.LVal) (time.Duration, bool)

GetDuration gets a time.Duration value from v and returns it.

func LoadPackage ¶

func LoadPackage(env *lisp.LEnv) *lisp.LVal

LoadPackage adds the time package to env

func Time ¶

func Time(t time.Time) *lisp.LVal

Time creates an immutable native wall-clock value representing t. It takes an independent snapshot of t's timezone object, preserving named-zone and daylight-saving rules but dropping Go monotonic clock metadata. The native payload is private; use Get to obtain an independent Go time.Time value. Callers must not mutate t's timezone concurrently with this call. This does not make capturing wall-clock time during template initialization equivalent to reading the clock independently during each cold load.
