Python Croniter get time in 24 hour format

Question

I have tried the Python croniter's get_prev() method to get the last scheduled time based on a cron string and current time.

When I tried it in windows machine it returned the value in 24 hour format. But when I tried the same code via AWS glue (possibly Linux) , it returned scheduled time in 12 hour format without AM/PM notation.

Is there any way to force the croniter to return time in 24 hour format always.

        currentTime=datetime.now()
        print(currentTime)
        cron = croniter(cron_str, currentTime)
        lastCronScheduleTime=cron.get_prev(datetime)
        print(lastCronScheduleTime)

Answer 1

In your example, get_prev returns a datetime.datetime instance.

When a datetime is passed to print(), it is first converted to string by calling its __str__ method. The __str__ method calls isoformat() (see python docs).

In other words, the output from your example should be in ISO 8601 format, which always uses 24-hour notation.

My guess is you are seeing different hour values because your Windows and Linux machines use different timezones, and datetime.now() returns a naive datetime in system's default timezone.
