"ddMM") are supported but must be used with care, as the resulting strings aren't always reliably readable (e.g. All other characters in the format string are included verbatim in the output string.įormats without separators (e.g. Two consecutive single quotes ("''") are replaced by a single quote in the output. This may depend on the operating system in use.Īny non-empty sequence of characters enclosed in single quotes will be included verbatim in the output string (stripped of the quotes), even if it contains formatting characters. The name used is the one provided by QTimeZone::displayName() with the QTimeZone::LongName type. Note that this gives no indication of whether the datetime was in daylight-saving time or standard time, which may lead to ambiguity if the datetime falls in an hour repeated by a transition between the two. The timezone name (for example "Europe/Berlin"). ![]() The timezone's offset from UTC with a colon between the hours and minutes (for example "+02:00"). The timezone's offset from UTC with no colon between the hours and minutes (for example "+0200"). In particular, toString() cannot parse this. Note that time zone abbreviations are not unique. ![]() ![]() The timezone abbreviation (for example "CEST"). In localized forms (only relevant to QLocale::toString()), the locale-appropriate text (returned by QLocale::amText() or QLocale::pmText()) is used without change of case. In localized forms (only relevant to QLocale::toString()), the locale-appropriate text is converted to lower-case. In localized forms (only relevant to QLocale::toString()), the locale-appropriate text is converted to upper-case. For example, "ss.zzz" would produce "00.250" for a time a quarter second into a minute. The fractional part of the second, to millisecond precision, including trailing zeroes where applicable (000 to 999). For example, "s.z" would produce "0.25" for a time a quarter second into a minute. Thus "s.z" reports the seconds to full available (millisecond) precision without trailing zeroes (0 to 999). The fractional part of the second, to go after a decimal point, without trailing zeroes. The whole second, with a leading zero where applicable (00 to 59) The whole second, without any leading zero (0 to 59) The minute with a leading zero (00 to 59) The minute without a leading zero (0 to 59) The hour with a leading zero (00 to 23, even with AM/PM display) The hour without a leading zero (0 to 23, even with AM/PM display) The hour with a leading zero (00 to 23 or 01 to 12 if AM/PM display) The hour without a leading zero (0 to 23 or 1 to 12 if AM/PM display) All conversion to and from string formats is done using the C locale. QTime objects can also be created from a text representation using fromString() and converted to a string representation using toString(). QTime provides a full set of operators to compare two QTime objects an earlier time is considered smaller than a later one if A. Correspondingly, the number of seconds or milliseconds between two times can be found using secsTo() or msecsTo(). The addSecs() and addMSecs() functions provide the time a given number of seconds or milliseconds later than a given time. ![]() The same information is provided in textual format by the toString() function. The hour(), minute(), second(), and msec() functions provide access to the number of hours, minutes, seconds, and milliseconds of the time. Unlike QDateTime, QTime knows nothing about time zones or daylight-saving time (DST).Ī QTime object is typically created either by giving the number of hours, minutes, seconds, and milliseconds explicitly, or by using the static function currentTime(), which creates a QTime object that represents the system's local time. QTime uses the 24-hour clock format it has no concept of AM/PM. QTime objects should be passed by value rather than by reference to const they simply package int. It provides functions for comparing times and for manipulating a time by adding a number of milliseconds. A QTime object contains a clock time, which it can express as the numbers of hours, minutes, seconds, and milliseconds since midnight.
