TimeISOT

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

Bases: astropy.time.TimeISO

ISO 8601 compliant date-time format “YYYY-MM-DDTHH:MM:SS.sss…”. This is the same as TimeISO except for a “T” instead of space between the date and time. For example, 2000-01-01T00:00:00.000 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(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)

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
