GiftsSecTime¶

class gdt.missions.gifts.time.GiftsSecTime(val1, val2, scale, precision, in_subfmt, out_subfmt, from_jd=False)[source]¶

Bases: TimeFromEpoch

Represents the number of seconds elapsed since Jan 1, 2001, 00:00:00 UTC, including leap seconds

Attributes Summary

`epoch`	Reference epoch time from which the time interval is measured.
`epoch_format`	Format of `epoch_val`
`epoch_scale`	The scale of `epoch_val`
`epoch_val`	The epoch in Terrestrial Time
`epoch_val2`
`in_subfmt`
`jd1`
`jd2`
`name`	Name of the mission
`out_subfmt`
`precision`
`scale`	Time scale.
`subfmts`
`unit`	unit in days
`value`	Return time representation from internal jd1 and jd2.

Methods Summary

`fill_value`(subfmt)	Return a value corresponding to J2000 (2000-01-01 12:00:00) in this format.
`set_jds`(val1, val2)	Initialize the internal jd1 and jd2 attributes given val1 and val2.
`to_value`([parent])	Return time representation from internal jd1 and jd2.

Attributes Documentation

epoch_format = 'iso'¶

Format of epoch_val

epoch_scale = 'tt'¶

The scale of epoch_val

epoch_val = '2001-01-01 00:01:04.184'¶

The epoch in Terrestrial Time

name = 'gifts'¶

Name of the mission

subfmts = (('float', <class 'numpy.float64'>, None, <ufunc 'add'>), ('long', <class 'numpy.longdouble'>, <function longdouble_to_twoval>, <function twoval_to_longdouble>), ('decimal', <class 'numpy.object_'>, <numpy.vectorize object>, <numpy.vectorize object>), ('str', <class 'numpy.str_'>, <numpy.vectorize object>, <numpy.vectorize object>), ('bytes', <class 'numpy.bytes_'>, <numpy.vectorize object>, <numpy.vectorize object>))¶

unit = 1.1574074074074073e-05¶

unit in days

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)¶: Initialize the internal jd1 and jd2 attributes given val1 and val2. For an TimeFromEpoch subclass like TimeUnix these will be floats giving the effective seconds since an epoch time (e.g. 1970-01-01 00:00:00).

to_value(parent=None, **kwargs)¶: Return time representation from internal jd1 and jd2. Subclasses that require parent or to adjust the jds should override this method.
