Applications dependent upon it include communication systems where networks need to be synchronised precisely, power grids, and finances, where timestamps accompany each transaction you make, and GPS - the Global Positioning System satellite navigation systems, which rely on time stamped signals to provide us with a precise location of a GPS receiver. By measuring the signal from four (or more) satellites, the user's position can be determined. The time measurement in GPS has to be incredibly accurate since light travels 30 centimetres in one nanosecond so even a tiny error in the time measurement could put you off course by many meters or even miles.

However, there are a number of special circumstances in which the entitlement to rest periods does not apply, for example, where the activities involve a need for continuity of service or production or where there is a foreseeable surge of activity. Also, if a shift worker changes shift, it may not be possible for them to take their full rest entitlement before starting the new pattern of work. In such a case the entitlement to daily and weekly rest does not apply. Weekly rest Employees will not normally be expected to work more than 48 hours in any seven-day period calculated over an averaging period of 17 weeks (unless extended in exceptional circumstances by agreement in partnership) at the employer's 'disposal' – this means the employer can tell them what they can or cannot do in that time Example 1: You might wish to cook a meal which needs to be in the oven for 6.30 hours. Let's say right now it is 11:20 and you want to find out when to set the oven timer to. You need to enter "11:20" in the "Time" box and then using the "add time" function you will enter "6" in the "hours" box and "30" in the "minutes" box. By hitting the "calculate" button you will be shown the result in the bottom, which in this case is 17:50, or 5:50 pm.Another example is the U.S. Federal Aviation Administration (FAA), which uses GPS to synchronize reporting of hazardous weather from its 45 Terminal Doppler Weather Radars covering the United States. This is just one scenario in which distributed networks of instruments must work together to precisely measure common events. Such networks require timing sources that can guarantee time accuracy at several points.

If a young worker is required to work more than four and a half-hours at a time, then they are entitled to a break of 30 minutes. A young worker is also entitled to twelve uninterrupted hours in each 24-hour period in which they work. Both these entitlements can only be altered or excluded in exceptional circumstances. Young workers are also entitled to 2 days off each week and this cannot be averaged over 2 weeks. Where employees are required as part of their contract to Stand-by within NHS Fife premises for the duration of a specified period, they are not free to pursue their time as their own, and so are regarded as working for the purposes of this agreement.You might not be paid for your rest breaks - your employment contract will say whether you are. Compensatory rest breaks

routine travel to and from home and the workplace if the person has a set workplace, for example a regular commute to an office or factory In circumstances where work is repetitive, continuous or requiring exceptional concentration Line Managers must ensure the provision of adequate rest breaks as an integral part of their duty to protect the health and safety of their employee. In such cases the advice of the Occupational Health and Safety Advisory Service should be sought. If you work for more than 6 hours a day, you’re entitled to an uninterrupted rest break of at least 20 minutes - for example a tea or lunch break. You must be allowed to take it during the day rather than at the beginning or end.The duties you undertake involve succeeding another officer at the same workstation according to a certain pattern. This is thought unlikely to apply to many police officers; This policy and associated appendices will be reviewed annually to ensure compliance with relevant and appropriate employment legislation. If someone thinks they're not getting the rest they're entitled to, they can first try resolving it by:

Employees are, therefore, now required as part of their contract of employment to inform their Line Manager of any other employment they may have when they commence employment with NHS Fife or if they commence secondary employment during their employment with NHS Fife. However, it is not necessary for the employee to give their Line Manager details of their other employment, including the type of work which they are performing, unless there is potential conflict of interests. If this is the case, the onus is on the employee to discuss this with their Line Manager. c) any additional period which is to be treated as working time for the purpose of these Regulations under a relevant agreement; This can be easily done by, including a special box in a time sheet asking whether or not the person has another employer or another post/s with NHS Fife. Provided this question has been asked, the requirement has been carried out, irrespective of whether or not the employee is willing to answer the question. This document is based on a question and answer format and provides responses to some commonly raised questions regarding compliance with the Working Time Regulations. Under the Working Time Regulations 1998, regulation 10, a worker is entitled to a rest period of 11 consecutive hours rest in each 24 hour period during which he works for his employer.Someone might ask for extra rest breaks due to a disability. The employer must agree to this if it's a reasonable adjustment. b) if it is to be for a specific period, clearly state the relevant dates and give the reason for the increased hours, e.g. the absence of a colleague or an increase in workload; A night worker is entitled to be transferred, whenever possible, to other work which is not at night, where a registered medical practitioner has advised NHS Fife that the employee is suffering from health problems connected with the fact that they work at night. Time spent “on call” if the worker is not required to be in the workplace unless a home is situated at the workplace and the employee is required to stay there whilst on call. Where an employee works less than an average of 48 hours per week (over a 17 week reference period), a copy of the contract of employment and any relevant duty and overtime sheets would be sufficient evidence that the 48 hour week is not being exceeded.
