obspy.core.event.base.CompositeTime

class CompositeTime(*args, **kwargs)[source]

Bases: obspy.core.event.base.__CompositeTime

Focal times differ significantly in their precision. While focal times of instrumentally located earthquakes are estimated precisely down to seconds, historic events have only incomplete time descriptions. Sometimes, even contradictory information about the rupture time exist. The CompositeTime type allows for such complex descriptions. If the specification is given with no greater accuracy than days (i.e., no time components are given), the date refers to local time. However, if time components are given, they have to refer to UTC.

Parameters:
  • year (int) – Year or range of years of the event’s focal time.
  • year_errors (QuantityError) – AttribDict containing error quantities.
  • month (int) – Month or range of months of the event’s focal time.
  • month_errors (QuantityError) – AttribDict containing error quantities.
  • day (int) – Day or range of days of the event’s focal time.
  • day_errors (QuantityError) – AttribDict containing error quantities.
  • hour (int) – Hour or range of hours of the event’s focal time.
  • hour_errors (QuantityError) – AttribDict containing error quantities.
  • minute (int) – Minute or range of minutes of the event’s focal time.
  • minute_errors (QuantityError) – AttribDict containing error quantities.
  • second (float) – Second and fraction of seconds or range of seconds with fraction of the event’s focal time.
  • second_errors (QuantityError) – AttribDict containing error quantities.
>>> print(CompositeTime(2011, 1, 1))
CompositeTime(year=2011, month=1, day=1)
>>> # Can also be instantiated with the uncertainties.
>>> print(CompositeTime(year=2011, year_errors={"uncertainty":1}))
CompositeTime(year=2011 [uncertainty=1])

Public Methods

clear

items
keys
pop If key is not found, d is returned if given, otherwise KeyError is raised.
popitem as a 2-tuple; but raise KeyError if D is empty.
setdefault
update If E present and has a .keys() method, does: for k in E: D[k] = E[k] If E present and lacks .keys() method, does: for (k, v) in E: D[k] = v In either case, this is followed by: for k, v in F.items(): D[k] = v

Warning

Private methods are mainly for internal/developer use and their API might change without notice.

_pretty_str Return better readable string representation of AttribDict object.
_repr_pretty_

Special Methods

__bool__
__contains__
__deepcopy__
__delattr__
__delitem__
__dir__ Default dir() implementation.
__eq__ Two instances are considered equal if all attributes and all lists are identical.
__format__ Default object formatter.
__getattr__ Py3k hasattr() expects an AttributeError no KeyError to be raised if the attribute is not found.
__getitem__

__reduce_ex__ Helper for pickle.
__repr__
__setattr__ Custom property implementation that works if the class is inheriting from AttribDict.
__setitem__
__setstate__
