I'd like to read the file as a pandas DataFrame with DATE, TIME and So the above views the timedelta64s as 8-byte ints and then does integer division to convert nanoseconds to seconds. And thus, I am doing this There are many ways to write a Python program to convert seconds to minutes and hours. The solution involves using the datetime. '00:00:10,000' -> 10 seconds 3. Converting from nanoseconds (int) to seconds (float) and then back to nanoseconds (int) to check if Time module in Python provides various time-related functions. Also, explore tools to convert second or nanosecond to other time units or learn more about time conversions. I know it is possible to convert nanoseconds in java to a timestamp like this: import java. time_ns() method of Time module is used to get the I'm working in python with a pandas df and trying to convert a column that contains nanoseconds to a time with days, hours, minutes and seconds, but I'm not succeeding. g. time() do something elapsed = (time. Method 2: Using total_seconds() Method I have a column of timestamps in seconds (since midnight) with nanosecond precisions like 34200. 36 I have a timestamp in epoch time with nanoseconds - e. We can create custom function or use time and datetime modules. Series. Obtaining POSIX/Unix Time in Nanoseconds While obtaining the time in seconds is The problem is that the float type starts to lose nanoseconds after 104 days. If secs is not provided or None, the current Enter time. Obtaining POSIX/Unix time in seconds or nanoseconds using Python 3 is straightforward with the help of the time module.
