cf.second

cf.second(value)[source]

Return a cf.Query object for date-time seconds.

In this context, any object which has a second attribute is considered to be a date-time variable.

If value is a cf.Query object then cf.second(value) is equivalent to value.addattr('second'). Otherwise cf.second(value) is equivalent to cf.eq(value, attr='second').

Parameters:
value:

Either the value that the second is to be compared with, or a cf.Query object for testing the second.

Returns:
out: cf.Query

The query object.

Examples:
>>> d = cf.dt(2002, 6, 16, 18, 30, 0)
>>> d == cf.second(0)
True
>>> d == cf.second(cf.le(30))
True
>>> d == cf.second(30)
False
>>> d == cf.second(cf.wi(0, 30))
True
