TimeString¶

class
astropy.time.
TimeString
(val1, val2, scale, precision, in_subfmt, out_subfmt, from_jd=False)[source]¶ Bases:
astropy.time.TimeUnique
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.
Attributes Summary

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.
-
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 thevalue
property. Subclasses that requireparent
or have other optional args forto_value
should compute and return the value directly.
