TimeFromEpoch
(val1, val2, scale, precision, in_subfmt, out_subfmt, from_jd=False)[source] [edit on github]¶ Bases:
astropy.time.TimeFormat
Base class for times that represent the interval from a particular epoch as a floating point multiple of a unit time interval (e.g. seconds or days).
Attributes Summary

scale
Time scale value
Methods Summary

(value) [edit on github]¶

set_jds
(val1, val2)[source] [edit on github]¶ 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).
-
to_value
(parent=None)[source] [edit on github]¶ Return time representation from internal jd1 and jd2. This is the base method that ignores
parent
and requires that subclasses implement thevalue
property. Subclasses that requireparent
or have other optional args forto_value
should compute and return the value directly.
