TimeISO¶

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

Bases: TimeString

ISO 8601 compliant date-time format “YYYY-MM-DD HH:MM:SS.sss…”. For example, 2000-01-01 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

value¶

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.

get_jds_fast(val1, val2)¶: Use fast C parser to parse time strings in val1 and get jd1, jd2

get_jds_python(val1, val2)¶: Parse the time strings contained in val1 and get jd1, jd2

mask_if_needed(value)¶

parse_string(timestr, subfmts)[source]¶: 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:

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
