class
astropy.time.
TimeFormat
(val1, val2, scale, precision, in_subfmt, out_subfmt, from_jd=False)[source] [edit on github]¶ Bases:
object
Base class for time representations.
Parameters: - val1 : numpy ndarray, list, number, str, or bytes
Values to initialize the time or times. Bytes are decoded as ascii.
- val2 : numpy ndarray, list, or number; optional
Value(s) to initialize the time or times. Only used for numerical input, to help preserve precision.
- scale : str
Time scale of input value(s)
- precision : int
Precision for seconds as floating point
- in_subfmt : str
Select subformat for inputting string times
- out_subfmt : str
Select subformat for outputting string times
- from_jd : bool
If true then val1, val2 are jd1, jd2

set_jds
(val1, val2)[source] [edit on github]¶ Set internal jd1 and jd2 from val1 and val2. Must be provided by derived classes.
-
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.
