# TimeString¶

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

Base class for string-like time representations.

This class assumes that anything following the last decimal point to the right is a fraction of a second.

This is a reference implementation can be made much faster with effort.

Methods Summary

 format_string(self, str_fmt, \*\*kwargs) Write time to a string using a given format. 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]) Return time representation from internal jd1 and jd2.

Methods Documentation

format_string(self, str_fmt, **kwargs)[source]

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)[source]

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

set_jds(self, val1, val2)[source]

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

str_kwargs(self)[source]

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.
