TimeYMDHMS#
- class astropy.time.TimeYMDHMS(val1, val2, scale, precision, in_subfmt, out_subfmt, from_jd=False)[source]#
Bases:
TimeUnique
ymdhms: A Time format to represent Time as year, month, day, hour, minute, second (thus the name ymdhms).
Acceptable inputs must have keys or column names in the “YMDHMS” set of
year
,month
,day
hour
,minute
,second
:Dict with keys in the YMDHMS set
NumPy structured array, record array or astropy Table, or single row of those types, with column names in the YMDHMS set
One can supply a subset of the YMDHMS values, for instance only ‘year’, ‘month’, and ‘day’. Inputs have the following defaults:
'month': 1, 'day': 1, 'hour': 0, 'minute': 0, 'second': 0
When the input is supplied as a
dict
then each value can be either a scalar value or an array. The values will be broadcast to a common shape.Example:
>>> from astropy.time import Time >>> t = Time({'year': 2015, 'month': 2, 'day': 3, ... 'hour': 12, 'minute': 13, 'second': 14.567}, ... scale='utc') >>> t.iso '2015-02-03 12:13:14.567' >>> t.ymdhms.year np.int32(2015)

Methods Documentation
- classmethod fill_value(subfmt)#
Return a value corresponding to J2000 (2000-01-01 12:00:00) in this format.
This is used as a fill value for masked arrays to ensure that any ERFA operations on the masked array will not fail due to the masked value.
- set_jds(val1, val2)[source]#
Set internal jd1 and jd2 from val1 and val2. Must be provided by derived classes.
- 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:
- Returns:
- value
numpy.array
,numpy.ma.array
Array or masked array of formatted time representation values
- value
