What does EPG offset mean?
An EPG offset is a player adjustment that shifts displayed programme-guide times. It can compensate for a documented time interpretation issue, but it should not be used to disguise an incorrect device clock or a channel mapped to the wrong regional schedule.
Why it matters
First establish whether the mismatch affects every channel equally. A global one-hour displacement differs from one incorrect row. Guide timestamps may already include time-zone information, so adding another manual correction can apply the shift twice. Note the original setting and change one control at a time, comparing a programme currently on air.
A practical example
For example, adjusting all listings because one delayed channel is wrong can break an otherwise correct guide. A targeted mapping correction is more appropriate when the problem belongs only to that channel.
