Zoho Books (Timesheet) : «The time spent for the day adds up to more than 24 hours. Please check and retry.»

I'm having trouble almost each time I try to star timer or log time, system says : « The time spent for the day adds up to more than 24 hours. Please check and retry.».

I didn't even loggued time for this project since several days. What's th problem? Bug??

Thanks,
