Timezone and differing file sizes issues

Mar 18, 2016 at 6:23 AM
Hi there,

I've uploaded some files from a local server to the Office 365 sharepoint cloud.

However I notice the times are different by the same offset of a few hours. Would this be a timezone issue?

Also some files have different file sizes. I would hate to lose data so could anyone tell me why this is so?

Regards
