obspy.core.event.CompositeTime

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

Bases: obspy.core.event.__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 (AttribDict) AttribDict containing error quantities.
  • month (int) Month or range of months of the event’s focal time.
  • month_errors (AttribDict) AttribDict containing error quantities.
  • day (int) Day or range of days of the event’s focal time.
  • day_errors (AttribDict) AttribDict containing error quantities.
  • hour (int) Hour or range of hours of the event’s focal time.
  • hour_errors (AttribDict) AttribDict containing error quantities.
  • minute (int) Minute or range of minutes of the event’s focal time.
  • minute_errors (AttribDict) 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 (AttribDict) 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])
