Yes-US and you are in USA? THis rather annoying and cumbersome feature has been reported there quite a few times-also from Asians-the ´system´'kind of automatic translated the times into EUR times, 4/5 hr difference. This also often leads to births days being 1 day ahead/after-so do not do that till In EUR here. So your assumption is wrong.
Thus-and thats best too: use other means to REServe-s listed by seewulf-often easier as app and saves money too. In this case-call SNCF-online can do via b-rail, but that needs pss cover nr (is on paper passes)-will take quite some time to get.
The advice from the experienced travellers in the community is to use other ways to make reservations than the Interrail/Eurail website. You can look at the guide in the link:

If you, after having looked at the guide, have questions about how to make specific reservation, please give your travel details (departure date, time and route) preferably in a new topic, and you will get advice. .
Hello, we're so sorry about this inconvenience. The best workaround for this issue at the moment is either to change your device's timezone settings to CET while reserving, or indeed, to try an alternative reservation methods in the post mentioned by @AnnaB
