In-Depth Information
As.an.example,.think.about.a.case.where.you.are.tasked.
with.establishing.exactly.when.a.document.was.created.and.
last.saved..According.to.the.evidence.you.have,.the.document.
was.saved.on.a.computer.in.Florida.on.December.16..You.
are.examining.the.computer.6.months.later.in.Colorado..The.
time.recorded.for.that.document's.creation.and.last.access.are.
recorded.as.noted.above.in.UTC..Your.job.will.be.to.consider.
what. the. time. zone. difference. would. be. for. Florida. during.
December.. That. would. be. Eastern. Daylight. time. (note. that.
between.November.and.March.we.have.to.adjust.for.daylight.
savings.time).which.is.-3.hours.difference.from.UTC..Your.
time. stamps. have. to. be. adjusted. to. relect. the. actual. local.
time.where.the.activity.took.place.
Now,. think. about. how. this. might. be. complicated. if. the.
activity.took.place.in.one.of.the.oddball.places.like.Indiana.
where. they. do. not. observe. daylight. savings. time,. or. other.
time.zones.like.some.of.the.Caribbean.Islands.that.choose.to.
adjust.their.time.by.only.a.half.hour.instead.of.an.hour..And.
of.course,.all.of.this.assumes.that.the.time.on.the.computer.
in.question.was.accurately.set.to.begin.with.and.was.not.tam-
pered.with.or.simply.lost.time.due.to.malfunction.of.the.time.
chip.or.power.loss.in.the.battery.
Because. this. can. be. so. important,. it. is. imperative. that.
some.type.of.auditing.or.other.means.of.veriication.of.the.
accuracy. and. integrity. of. the. time. be. established.. If. you.
are.in.the.position.of.needing.to.prove.the.integrity.of.the.
time,.you.may.need.to.gather.corroborating.evidence.such.
as.other.devices.that.show.the.same.time.for.the.activity.in.
question,. or. perhaps. some. type. of. documentation. of. the.
time.having.been.audited.and.monitored.for.accuracy.on.a.
regular.basis.
As. an. organization. that. might. have. to. prove. the. integ-
rity.of.time.information.recorded.on.its.electronic.data,.it.is.
important.to.maintain.that.type.of.auditable.documentation.
to.show.that.you.have.some.type.of.time.server.or.standard.
that.is.monitored.regularly.and.carefully.maintained.
