src Duration abs()

Absolute value - if this is a negative duration, then return its positive value.

src static Duration boot()

Get the system timer at boot time of the Fantom VM.

src Duration clamp(Duration min, Duration max)

Clamp this duration between the min and max. If it's less than min then return min, if it's greater than max return max, otherwise return this duration itself.

src virtual override Int compare(Obj obj)

Compare based on nanosecond ticks.

src const static Duration defVal

Default value is 0ns.

src @Operator
Duration div(Int b)

Divide this by b. Shortcut is a/b.

src @Operator
Duration divFloat(Float b)

Divide this by b. Shortcut is a/b.

src virtual override Bool equals(Obj? obj)

Return true if same number nanosecond ticks.

src Duration floor(Duration accuracy)

Return a new Duration with this duration's nanosecond ticks truncated according to the specified accuracy. For example floor(1min) will truncate this duration such that its seconds are 0.0.

src static Duration fromIso(Str s, Bool checked := true)

Parse a duration according to ISO 8601. If invalid format and checked is false return null, otherwise throw ParseErr. The following restrictions are enforced:

• Cannot specify a Y year or M month component since it is ambiguous
• Only the S seconds component may include a fraction
• Only nanosecond resolution is supported See toIso for example formats.

src static new fromStr(Str s, Bool checked := true)

Parse a Str into a Duration according to the Fantom literal format. If invalid format and checked is false return null, otherwise throw ParseErr. The following suffixes are supported:

ns:   nanoseconds  (x 1)
ms:   milliseconds (x 1,000,000)
sec:  seconds      (x 1,000,000,000)
min:  minutes      (x 60,000,000,000)
hr:   hours        (x 3,600,000,000,000)
day:  days         (x 86,400,000,000,000)

Examples:

Duration.fromStr("4ns")
Duration.fromStr("100ms")
Duration.fromStr("-0.5hr")

src virtual override Int hash()

Return ticks().

src static new make(Int ticks)

Create a Duration which represents the specified number of nanosecond ticks.

src Duration max(Duration that)

Return the maximum duration between this and that.

src const static Duration maxVal

Max value is equivalent to make(Int.maxVal).

src Duration min(Duration that)

Return the minimum duration between this and that.

src const static Duration minVal

Min value is equivalent to make(Int.minVal).

src @Operator
Duration minus(Duration b)

Subtract b from this. Shortcut is a-b.

src @Operator
Duration mult(Int b)

Multiply this with b. Shortcut is a*b.

src @Operator
Duration multFloat(Float b)

Multiply this with b. Shortcut is a*b.

src @Operator
Duration negate()

Negative of this. Shortcut is -a.

src static Duration now()

Get the current value of the system timer. This method returns a relative time unrelated to system or wall-clock time. Typically it is the number of nanosecond ticks which have elapsed since system startup.

src static Int nowTicks()

Convenience for now.ticks.

src @Operator
Duration plus(Duration b)

Add this with b. Shortcut is a+b.

src Int ticks()

Return number of nanosecond ticks.

src Str toCode()

Get this Duration as a Fantom code literal.

src Int toDay()

Get this duration in 24 hour days. Any fractional days are truncated with a loss of precision.

src Int toHour()

Get this duration in hours. Any fractional hours are truncated with a loss of precision.

src Str toIso()

Format this duration according to ISO 8601. Also see fromIso.

Examples:

8ns.toIso             =>  PT0.000000008S
100ms.toIso           =>  PT0.1S
(-20sec).toIso        =>  -PT20S
3.5min.toIso          =>  PT3M30S
1day.toIso            =>  PT24H
(1day+2hr+3min).toIso =>  P1DT2H3M

src Str toLocale()

Return human friendly string representation. TODO: enhance this for pattern

src Int toMillis()

Get this duration in milliseconds. Any fractional milliseconds are truncated with a loss of precision.

src Int toMin()

Get this duration in minutes. Any fractional minutes are truncated with a loss of precision.

src Int toSec()

Get this duration in seconds. Any fractional seconds are truncated with a loss of precision.

src virtual override Str toStr()

Return string representation of the duration which is a valid duration literal format suitable for decoding via fromStr.

src static Duration uptime()

Get the duration which has elapsed since the Fantom VM was booted which is now - boot.
