Attributes Documentation

cache¶: Return the cache associated with this instance.

in_subfmt¶

jd1¶

jd2¶

jd2_filled¶

mask¶

masked¶

name = 'jd'¶

out_subfmt¶

precision¶

scale¶: Time scale

subfmts = (('float', <class 'numpy.float64'>, None, <ufunc 'add'>), ('long', <class 'numpy.float128'>, <function longdouble_to_twoval>, <function twoval_to_longdouble>), ('decimal', <class 'numpy.object_'>, <numpy.vectorize object>, <numpy.vectorize object>), ('str', <class 'numpy.str_'>, <numpy.vectorize object>, <numpy.vectorize object>), ('bytes', <class 'numpy.bytes_'>, <numpy.vectorize object>, <numpy.vectorize object>))¶

unit = 1.0¶

value¶

Methods Documentation

mask_if_needed(value)¶

set_jds(val1, val2)¶: Set internal jd1 and jd2 from val1 and val2. Must be provided by derived classes.

to_value(**kwargs)¶

Return time representation from internal jd1 and jd2 in specified out_subfmt.

This is the base method that ignores parent and uses the value property to compute the output. This is done by temporarily setting self.out_subfmt and calling self.value. This is required for legacy Format subclasses prior to astropy 4.0 New code should instead implement the value functionality in to_value() and then make the value property be a simple call to self.to_value().

Parameters:

parentobject: Parent Time object associated with this TimeFormat object
out_subfmtpython:str or python:None: Output subformt (use existing self.out_subfmt if None)

Returns:

valuenumpy.array, numpy.ma.array: Array or masked array of formatted time representation values
