Daylight_saving_time
dst's clock shifts have the obvious disadvantage of complexity. people must remember to change their clocks; this can be time-consuming, particularly for mechanical clocks that cannot be moved backward safely. people who work across time zone boundaries need to keep track of multiple dst rules, as not all locations observe dst or observe it the same way. the length of the calendar day becomes variable; it is no longer always 24 hours. disruption to meetings, travel, broadcasts, billing systems, and records management is common, and can be expensive. during an autumn transition from 02:00 to 01:00, a clock reads times from 01:00:00 through 01:59:59 twice, possibly leading to confusion.
What do people often have trouble remembering to do for DST?

Daylight_saving_time
damage to a german steel facility occurred during a dst transition in 1993, when a computer timing system linked to a radio time synchronization signal allowed molten steel to cool for one hour less than the required duration, resulting in spattering of molten steel when it was poured. medical devices may generate adverse events that could harm patients, without being obvious to clinicians responsible for care. these problems are compounded when the dst rules themselves change; software developers must test and perhaps modify many programs, and users must install updates and restart applications. consumers must update devices such as programmable thermostats with the correct dst rules, or manually adjust the devices' clocks. a common strategy to resolve these problems in computer systems is to express time using the coordinated universal time (utc) rather than the local time zone. for example, unix-based computer systems use the utc-based unix time internally.

Daylight_saving_time
as explained by richard meade in the english journal of the (american) national council of teachers of english, the form daylight savings time (with an "s") was already in 1978 much more common than the older form daylight saving time in american english ("the change has been virtually accomplished"). nevertheless, even dictionaries such as merriam-webster's, american heritage, and oxford, which describe actual usage instead of prescribing outdated usage (and therefore also list the newer form), still list the older form first. this is because the older form is still very common in print and preferred by many editors. ("although daylight saving time is considered correct, daylight savings time (with an "s") is commonly used.") the first two words are sometimes hyphenated (daylight-saving[s] time). merriam-webster's also lists the forms daylight saving (without "time"), daylight savings (without "time"), and daylight time.

the iana time zone database maps a name to the named location's historical and predicted clock shifts. this database is used by many computer software systems, including most unix-like operating systems, java, and the oracle rdbms; hp's "tztab" database is similar but incompatible. when temporal authorities change dst rules, zoneinfo updates are installed as part of ordinary system maintenance. in unix-like systems the tz environment variable specifies the location name, as in tz=':america/new_york'. in many of those systems there is also a system-wide setting that is applied if the tz environment variable isn't set: this setting is controlled by the contents of the /etc/localtime file, which is usually a symbolic link or hard link to one of the zoneinfo files. internal time is stored in timezone-independent epoch time; the tz is used by each of potentially many simultaneous users and processes to independently localize time display.

xinjiang, china; argentina; chile; iceland; russia and other areas skew time zones westward, in effect observing dst year-round without complications from clock shifts. for example, saskatoon, saskatchewan, is at 106°39′ w longitude, slightly west of center of the idealized mountain time zone (105° w), but the time in saskatchewan is central standard time (90° w) year-round, so saskatoon is always about 67 minutes ahead of mean solar time, thus effectively observing daylight saving time year-round. conversely, northeast india and a few other areas skew time zones eastward, in effect observing negative dst. the united kingdom and ireland experimented with year-round dst from 1968 to 1971 but abandoned it because of its unpopularity, particularly in northern regions.

western france, spain, and other areas skew time zones and shift clocks, in effect observing dst in winter with an extra hour in summer. nome, alaska, is at 165°24′ w longitude, which is just west of center of the idealized samoa time zone (165° w), but nome observes alaska time (135° w) with dst, so it is slightly more than two hours ahead of the sun in winter and three in summer. double daylight saving time has been used on occasion; for example, it was used in some european countries during and shortly after world war ii when it was referred to as "double summer time". see british double summer time and central european midsummer time for details.
