st.timedeltas() Generates timedelta objects. st.one_of() Choose one of the given strategies with equal probability. st.sampled_from() Chooses values from a given sequence with equal probability. st.lists() Generates lists of elements. st.dates() Generates date objects. st.datetimes(...
New method: the datetime module’s timedelta class gained a total_seconds() method that returns the number of seconds in the duration. (Contributed by Brian Quinlan; bpo-5788.) New method: the Decimal class gained a from_float() class method that performs an exact conversion of a floating-...

When working with time deltas and time zones, users may find it more convenient to use the arcpy.time module instead of the core Python datetime module. Time classes ClassDescription EsriTimeDelta The EsriTimeDelta class represents a duration, the difference between two dates or times. TimeZone...

To use the new monotonic clock functionality, all calls to IOLoop.add_timeout must be either pass a datetime.timedelta or a time relative to IOLoop.time, not time.time. (time.time will continue to work only as long as the IOLoop’s time_func argument is not used). New convenience ...
