Here's what I would try:
Field('difference', compute=lambda u: (u['DT_FECHAMENTO '] -
u['DT_ABERTURA ']), label='Difference')
This is untested. I haven't used compute fields based on a math
function before, but like I said, this is what I'd try first.
Hope this helps.

People,
How can I make the field NR_INDISPONIBILIDADE the table below
(chamado) in a computed field with the difference between the field
dates DT_FECHAMENTO and DT_ABERTURA.
Thank you,
db.define_table("chamados"
,Field('ID_CHAMADOS',type='id',readable=False)
,Field('ID_TECNICOS',type='integer',notnull=True,label='Técnico')
,Field('ID_CIRCUITOS',type='integer',notnull=True,label='Circuito')
,Field('NR_CHAMADO',type='string',notnull=False,label='Chamado')
,Field('DT_ABERTURA',type='datetime',notnull=True,label='Abertura')
,Field('DT_FECHAMENTO',type='datetime',notnull=False,label='Fechamento')
,Field('NR_INDISPONIBILIDADE',type='double',notnull=False,label='Indisponibilidade')
,Field('FL_OFENSOR',type='boolean',label='Ofensor',default=True)
,migrate=False
)
