Calculations can also be done using local time once the expected time difference is known. The fact that time zones around the world are all calculated as an offset or difference from standard time makes it easy to know the time of a place by just knowing the time zone it falls in and the standard time at the current moment. Every place on Earth is measured either in degrees east or degrees west of this line. The Meridian, after which GMT is named, is used to represent 0 degrees longitude (although it is not truly 0 degrees). In 1847, the British railroads accepted GMT as a standard. GMT was the same as Universal Time up until 1972. To calculate the time zone an area theoretically falls in, the measurement of the area’s longitudinal coordinate is divided by 15. This means that, in the spring, a clock will go from 4:00 Standard Time to 5:00 DST. World Clocks are adjusted forward by one hour in the early spring and then set back by one hour in the autumn. Therefore, for half of the year some countries adjust their clocks by one hour. For instance, Saudi Arabia, which is 3 hours ahead of the UK, has a time zone of “GMT +3” and Colombia, which is 5 hours behind the UK, has a time zone of “GMT -5”.ĭaylight Savings Time (DST) is practiced in certain parts of the world in order to allow for more hours of daylight during the working day. The UK sets the standard for Greenwich Mean Time at “ GMT 0” and other countries can calculate their time zone in accordance with how many hours they are ahead of or behind the UK. ![]() ![]() There are 24 different time zones on earth to correlate with the 24 hours in each day and which are displayed in our time zone map here at World Clock. Time zones are regions of the earth divided by lines of longitude. However, there is no actual time difference between GMT and UTC and therefore the two can be used interchangeably. There are two standards by which a country’s time zone is categorized the older of the two standards is Greenwich Mean Time (GMT) and the more modern of the two standards is Coordinated Universal Time ( UTC). Whether you’re looking to book a flight, schedule an international teleconference, use our time zone converter or our time zone map and observe the trading hours of an overseas business, can show you the time in a matter of seconds. With incomparable time-telling precision, World Clock is the perfect point of reference for travelers and business people alike. If you don't want to use a conversion calculator (like the one above), another basic tool is a decimal conversion chart. When you have to turn, say, 17 hours and 25 minutes in decimals, you can easily check the conversion table and see that this equals 17.42 provides accurate world time, statistics and weather in major cities across the world. Manually converting employee hours and minutes to decimal values (hundredths) is time-consuming and prone to errors. Minutes to Decimals Time Conversion Chart To get her net pay, you'll have to factor in deductions and taxes. Melanie’s weekly pay based on her total hours is then: 37.7 hours x $15 = $565.50 This means that 37 hours and 42 minutes convert to 37.7 hours in decimal time. Then you have to add the converted minutes to the hours: 37 + 0.7 = 37.7 The correct calculation is thus: 42 minutes/60 = 0.7 You have to convert minutes into decimals. This is wrong since, once again, an hour is made up of 60 minutes, and not 100. However, if you take 37 hours and 42 minutes as they are, you would get 37.42. Then you need to multiply the number of hours she worked by her hourly rate to determine her weekly total pay. The hourly rate that she receives is $15.įirst, you have to take the information from her weekly time card or timesheet that contains her clock-in and clock-out times (ee timecard templates here). ![]() This week she has worked 37 hours and 42 minutes (and no overtime hours). It is also essential for keeping track of lunch breaks, general break time, overtime pay, and holidays. This is crucial for hourly staff members, who are often non-exempt employees. You need to convert time into decimal numbers to figure out your employees' exact pay rate. Why? Because one hour contains 60 minutes, and not 100. But hours and minutes aren’t directly equal to money owed. Usually you get records of employees’ time worked in hours and minutes. Wait…so why do I need time clock conversion?
