TimeYearDayTime

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

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 Documentation

format_string(self, 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(self, value)

parse_string(self, timestr, subfmts)

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

set_jds(self, val1, val2)

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

str_kwargs(self)

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

to_value(self, parent=None)

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.
