No, it means they get an extra 2h of voting with no legislation backing that nor a precedent to go after.
Have polling stations open for a week, run them 24 hours on election day. Have so many that there's never a queue, and no one complains that they have to go far. That's democracy. The price is negligible.
Unless you're relying on suppressing the capacity of certain parts of your population to vote to win an election, like my country's right wing government has done, because last minute enrollment voters tend to not vote for them.

Polls were closed in some places, voting boxes sealed, and had to be reopened.
While not necessarily bad, it can create fraud suspicions. Just arrange a longer voting time from the get go. Else it looks you are stalling and boosting turnout out for your side.
PS it’s quite common in some countries to put people on buses and make them vote in exchange of money.
