TimeUnique

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

Bases: astropy.time.TimeFormat

Base class for time formats that can uniquely create a time object without requiring an explicit format specifier. This class does nothing but provide inheritance to identify a class as unique.

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(parent=None, out_subfmt=None)

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

parentobj

Parent Time object associated with this TimeFormat object

out_subfmtstr or 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
