TimeUnix

class astropy.time.TimeUnix(val1, val2, scale, precision, in_subfmt, out_subfmt, from_jd=False)

Bases: astropy.time.TimeFromEpoch

Unix time: seconds from 1970-01-01 00:00:00 UTC. For example, 946684800.0 in Unix time is midnight on January 1, 2000.

NOTE: this quantity is not exactly unix time and differs from the strict POSIX definition by up to 1 second on days with a leap second. POSIX unix time actually jumps backward by 1 second at midnight on leap second days while this class value is monotonically increasing at 86400 seconds per UTC day.

Methods Documentation

set_jds(val1, val2)

Initialize the internal jd1 and jd2 attributes given val1 and val2. For an TimeFromEpoch subclass like TimeUnix these will be floats giving the effective seconds since an epoch time (e.g. 1970-01-01 00:00:00).
