The <column-with-longType> is the column that has the LongType data from which we want to extract the timestamps with precision up to nanoseconds. scala - Blame DurationConversions. Our conversions provide a quick and easy way to convert between Time units. Non-finite durations are represented as Duration. Convert 3866 Nanosecond (ns) to Second (s) instantly. Dec 30, 2023 · In this tutorial, we’ll learn how to calculate the elapsed time of a method in Scala using different approaches. 1. SECONDS. Using System Time The most naive approach relies on using the Java API method System. Returns the number of nanoseconds as floating point number, scaled down to the given unit. Then, we create a new convertedDF DataFrame with the <formatted-datetime-column> column, which has the timestamp with nanosecond precision in a StringType format. Using a Wrapper Function The previous approach offers us an insight into the performance of a method, but it’s a bit cumbersome to use. The result may not precisely represent this duration due to the Double datatype's inherent limitations (mantissa size effectively 53 bits). Dec 12, 2015 · Is there a way to convert a timestamp value with nano seconds to timestamp in spark. Fast and accurate time unit conversion tool. Apr 26, 2025 · To retain nanosecond precision, you must create a User-Defined Function (UDF) that processes the LongType column and converts it into a properly formatted string representation of the timestamp, keeping the nanosecond component intact. 12.
