ConvertTZ converts a time.Time into a new time.Time in a timezone specified by tz.

NewOSClock returns a Clock interface implementation that uses time.Now.

NewTimedSlidingWindowI64 creates a new time-based sliding window for int64 value aggregation.

OverwriteTZ takes the literal values of y/m/d/h/m/s of a time.Time and uses them together with a supplied timezone to form a new time.Time, effectively "overwriting" the original time.Time's tz.

SmartParse parses a date time string and returns a time.Time and a tz flag indicates whether the date time string contains tz info.

TimedSlidingWindowI64 offers a way to aggregate int64 values over a time-based sliding window.

Clock tells the current time.
