tzinfo.utcoffset(d) does not return None Otherwise, d is naive. A time item t knows if both of the following hold: t. tzinfo is not None t. tzinfo.utcoffset(None) does not return None. Otherwise, t is naive. The difference in between aware and naive does not apply to timedelta items. timedelta Items A timedelta things represents a period, the difference between two dates or times.

timedelta(days=0, seconds=0, microseconds=0, milliseconds=0, minutes=0, hours=0, weeks=0) All arguments are optional and default to 0. Arguments might be integers or floats, and might be favorable or negative. Only days, seconds and microseconds are saved internally. Arguments are transformed to those units: A millisecond is converted to 1000 microseconds. A minute is converted to one minute.

A week is transformed to 7 days. and days, seconds and split seconds are then normalized so that the representation is distinct, with 0 > > delta=timedelta(... seconds =27, ... microseconds=10, ... milliseconds =29000, ... minutes=5, ... hours= 8, ... weeks=2 ...)>> > # You Can Try This Source , seconds, and split seconds remain >> > delta datetime. timedelta(days=64, seconds=29156, microseconds = 10 )If any argument is a float and there are fractional microseconds, the fractional microseconds left over from all arguments are integrated and their sum is rounded to the closest split second using round-half-to-even tiebreaker.

If the normalized worth of days lies outside this range, Overflow, Mistake is raised. Note that normalization of negative worths might be surprising initially. For example: >> > from datetime import timedelta >> > d = timedelta(microseconds=-1) >> > (d. days, d. seconds, d. split seconds) (-1, 86399, 999999) Class characteristics: timedelta.

timedelta. max The most favorable timedelta item, timedelta(days=999999999, hours=23, minutes=59, seconds=59, split seconds=999999). timedelta. resolution The tiniest possible distinction in between non-equal timedelta items, timedelta(split seconds=1). Note that, because of normalization, timedelta. max > -timedelta. min. -timedelta. max is not representable as a timedelta item. Instance qualities (read-only): Attribute Worth days Between -999999999 and 999999999 inclusive seconds Between 0 and 86399 inclusive split seconds In between 0 and 999999 inclusive Supported operations: Operation Outcome t1 = t2 + t3 Amount of t2 and t3.
