Usage

Parsing duration strings

from philiprehberger_duration import parse

parse("2h30m")              # 9000.0
parse("1 day, 3 hours")    # 97200.0
parse("500ms")             # 0.5
parse("1w 2d")             # 777600.0
parse("2.5h")              # 9000.0
parse("150m")              # 9000.0

ISO 8601 parsing

from philiprehberger_duration import parse

parse("PT2H30M")           # 9000.0
parse("P1DT12H")           # 129600.0
parse("PT1M30S")           # 90.0
parse("PT0.5S")            # 0.5

Colon format parsing

from philiprehberger_duration import parse

parse("1:30:00")           # 5400.0
parse("1:05")              # 65.0
parse("1:05:30.500")       # 3930.5

Formatting seconds

from philiprehberger_duration import format

format(9000)                        # "2h 30m"
format(9000, style="long")         # "2 hours, 30 minutes"
format(9000, style="colon")        # "2:30:00"
format(9000, style="iso")          # "PT2H30M"
format(90061.5, style="short")    # "1d 1h 1m 1s 500ms"

Duration object

from philiprehberger_duration import Duration

d = Duration.from_seconds(9000)
d.hours    # 2
d.minutes  # 30

# Arithmetic
d2 = d + Duration(minutes=15)
d3 = d * 2
d4 = d - Duration(minutes=10)
d5 = d / 2
d6 = d // 3

# Comparisons
Duration.from_seconds(60) < Duration.from_seconds(120)   # True
Duration.from_seconds(60) == Duration(minutes=1)          # True
Duration(hours=1) >= Duration(minutes=30)                 # True

# Convert to timedelta
td = d.to_timedelta()

# String representation (short format)
str(d)  # "2h 30m"

Timedelta conversion

from philiprehberger_duration import Duration

d = Duration(hours=1, minutes=30, milliseconds=500)
td = d.to_timedelta()  # datetime.timedelta(seconds=5400, microseconds=500000)

API Reference

Function / Class	Description
parse(s: str) -> float	Parse a human-readable duration string to seconds.
format(seconds: float, *, style: str = "short") -> str	Format seconds to a human-readable string. Styles: "short", "long", "colon", "iso".
