What's Wrong?

Timestamps in transcript reflect the current time, not the time the message was sent.

What Should Happen?

Timestamps in transcript should reflect the time that the message was sent, not the current time

Error Messages/Logs

Steps to Reproduce

Steps to reproduce:

• type /resume, choose an old conversation
• ctrl-o to view transcript
• observe that the timestamps reflect the current time, not when the messages were sent

It appears this also occurs for current conversations.
