TimeYearDayTime

class astropy.time.TimeYearDayTime(val1, val2, scale, precision, in_subfmt, out_subfmt, from_jd=False)[source]

Bases: astropy.time.TimeISO

Year, day-of-year and time as “YYYY:DOY:HH:MM:SS.sss…”. The day-of-year (DOY) goes from 001 to 365 (366 in leap years). For example, 2000:001:00:00:00.000 is midnight on January 1, 2000.

The allowed subformats are:

  • ‘date_hms’: date + hours, mins, secs (and optional fractional secs)

  • ‘date_hm’: date + hours, mins

  • ‘date’: date

Methods Summary

format_string(str_fmt, **kwargs)

Write time to a string using a given format.

mask_if_needed(value)

parse_string(timestr, subfmts)

Read time from a single string, using a set of possible formats.

set_jds(val1, val2)

Parse the time strings contained in val1 and set jd1, jd2

str_kwargs()

Generator that yields a dict of values corresponding to the calendar date and time for the internal JD values.

to_value([parent, out_subfmt])

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

Methods Documentation

format_string(str_fmt, **kwargs)

Write time to a string using a given format.

By default, just interprets str_fmt as a format string, but subclasses can add to this.

mask_if_needed(value)
parse_string(timestr, subfmts)

Read time from a single string, using a set of possible formats.

set_jds(val1, val2)

Parse the time strings contained in val1 and set jd1, jd2

str_kwargs()

Generator that yields a dict of values corresponding to the calendar date and time for the internal JD values.

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
