PPCGeeks - SMS timestamp in roaming...

after a mild amount of searching, i've found no information pertaining to my issue so any help would be appreciated!
when i'm in roaming (which is about 80% of my week!) my incoming text messages get a random timestamp jumping all over the place. some of the texts come in with a timestamp of hours ago and some come in with a timestamp of the future!

i know that they're inaccurate because it happens while having a discussion with a person. the outgoing timestamp is correct but their reply is some random time, placing the text at the bottom, top, or middle of my sms overview, which is slightly frustrating.

does anyone know what i can do about this (if anything)?
