Twitter – Display multiple Trending Topics at the same time

You may need to check your settings on both services to make sure you have chosen the correct time-zone. If you're in a country that doesn't observe DST, make sure you select the correct time-zone or un-tick the box to adjust for DST. I honestly don't use Facebook or Twitter (I'm a bit of a paranoid security geek), but I do know that Facebook won't let you change your time-zone after your account is set (Facebook Help Centre). And Twitter, on the flip-side does "hours ago..." rather than a specific date/time. There might be an account-setting that adjusts that to your local time-zone, but that's up to you to look for.
