And it'll bring:

Timezone                  | Time
_________________________ | ___________________________
America/New_York          | 2024-10-27 21:10 EDT -04:00

You can set the local flag to show your local timezone.

$ ontime-cli compare --timezone America/New_York --timezone Europe/London --timezone Europe/Berlin --local

And it'll bring:

Timezone                  | Time
_________________________ | ___________________________
America/Sao_Paulo (Local) | 2024-10-27 22:10 -03 -03:00

Also, it is possible add and subtract hours for your local time. The follow example, we're comparing Date Time 3 hours from current time.

$ ontime-cli compare --timezone America/New_York --timezone  Europe/London --timezone Europe/Berlin --from-now 3

The next example, 3 hours ago.

$ ontime-cli compare --timezone America/New_York --timezone Europe/London --timezone Europe/Berlin --ago 3
