In my dataset I have two timestamp columns. The first is microseconds since application was started – e.g., 1400805323. The second is described as 64bit timestamp which I’m hoping will indicate clock time, using NTP format of number of seconds from 1/1/1901.
Example of ’64bit’ timestamps:
129518309081725000
129518309082059000
129518309082393000
129518309082727000
129518309083060000
129518309083394000
129518309083727000
Is there any matlab/python code that could convert this into a readable format?
Any help much appreciated,
Steve
Assuming that these values were generated today, June 6th 2011, these values look like number of 100-nanosecond intervals since Jan 1st year 1601. This is how Windows NT stores FILETIME. For more concentrated info on this read this blog post of Raymond Chen. These articles also show how to convert it to anything else
