Serial monitor in Arduino IDE v. 2.0.0-rc4 doesn't pad timestamps correctly

[colde]

Describe the bug
When enabling timestamps in the serial monitor, timestamps might be formatted as 18:2:13.521 instead of as expected 18:02:13.521

I.e. this is the data i got in my console:

17:56:13.570 -> New message received
17:58:24.586 -> New message received
18:0:14.054 -> New message received
18:2:13.521 -> New message received
18:2:18.212 -> New message received

To Reproduce
Steps to reproduce the behavior:

1. Have a board connected that outputs serial data
2. Enable the serial monitor timestamp feature
3. Wait for a time where between 0 and 9 minutes past the hour
4. See error

Expected behavior
The timestamps should prepend a 0 for single digit minutes

Desktop (please complete the following information):

• OS: macOS Monterey 12.2.1
• Version: 2.0.0-rc4

Hi @colde. Thanks for taking the time to submit an issue.

I see we have another report about this at #580.

It is best to have only a single issue per subject so we can consolidate all relevant discussion to one place, so I'll go ahead and close this in favor of the other.

If you end up with additional information to share, feel free to comment in the other thread.

Apologies. My search didn't find that.
