time of day (TOD)
In Germany and in various other European countries, the time of day is given in hours and minutes, or seconds. According to this time specification, a day is divided into 24 hours. The hours run from 0:00 to 24:00 and are counted continuously.
It is different in Great Britain or in the USA, where the time of day in the time range from 0:00 o' clock to 11:59 o'clock at noon is designated with the addition AM, which stands for Ante Meridiem - before noon - and the time range from 12:00 o'clock to 23:59 o'clock with PM, which stands for Post Meridiem - after noon.
