TimeFormat

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

Attributes Summary

scale Time scale
value

Methods Summary

set_jds(val1, val2) Set internal jd1 and jd2 from val1 and val2.
to_value([parent]) Return time representation from internal jd1 and jd2.

Methods Documentation

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 the value property. Subclasses that require parent or have other optional args for to_value should compute and return the value directly.
