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
Return the cache associated with this instance.
Time scale
Methods Summary
format_string
(str_fmt, **kwargs)Write time to a string using a given format.
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
Generator that yields a dict of values corresponding to the calendar date and time for the internal JD values.
to_value
([parent, out_subfmt])Return time representation from internal jd1 and jd2 in specified
out_subfmt

Methods Documentation
-
format_string
(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
(value)¶
-
parse_string
(timestr, subfmts)[source]¶ Read time from a single string, using a set of possible formats.
-
str_kwargs
()[source]¶ 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 thevalue
property to compute the output. This is done by temporarily settingself.out_subfmt
and callingself.value
. This is required for legacy Format subclasses prior to astropy 4.0 New code should instead implement the value functionality into_value()
and then make thevalue
property be a simple call toself.to_value()
.- Parameters
parent : obj
Parent
Time
object associated with thisTimeFormat
objectout_subfmt : str or
None
Output subformt (use existing self.out_subfmt if
None
)- Returns
value : numpy.array, numpy.ma.array
Array or masked array of formatted time representation values
