This format does include a year 0, which is 1BC in other formats. This is what you get when you call toISOString().

ECMAScript does standardize one format: ISO 8601. That is: toString(), toLocaleString(), toUTCString() and friends. This understanding is reflected when printing or parsing dates in one of the formats not standardized by ECMAScript. Common human language does not have a year 0.
There are different date formats with different understandings of negative years. Therefore, constructing a Date value in JS and converting it to a string using the locale-aware functions can yield a result incorrect by one hour, if DST is currently in effect, while it was not for the time specified, or vice versa. ECMA-262 specifies that historical dates should be intrepreted by projecting the current rules for daylight-saving onto past years, while Qt uses historical data (where available) to determine whether daylight-saving was in effect for a given date. Using the locale-aware functions to perform date or time formatting can result in incorrectly formatted times, due to an inconsistency in specification between Qt and JS.
If the date is invalid, an empty string will be returned. Two consecutive singlequotes ("''") are replaced by a singlequote in the output.Įxample format strings (assuming that the QTime is 14:13:09.042) Any sequence of characters that are enclosed in singlequotes will be treated as text and not be used as an expression. ap will be replaced by either "am" or "pm".Īll other input characters will be ignored. AP will be replaced by either "AM" or "PM". The milliseconds with leading zeroes (000 to 999) The milliseconds without leading zeroes (0 to 999) The second with a leading zero (00 to 59) The second without a 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 TimeSpan object in the $90mins variable.The hour without a leading zero (0 to 23 or 1 to 12 if AM/PM display) The second command uses the Adjust parameter of Set-Date to adjust the date by the value of Interval, and saves it in the $90mins variable. The first command uses the New-TimeSpan cmdlet to create a TimeSpan object with a 90-minute These commands advance the system time on the local computer by 90 minutes. Set-Date -Date $T Example 4: Add 90 minutes to the system clock The second command uses the Date parameter to pass the DateTime object in $T to the The first command gets the date and stores it in $T. These commands change the system date and time on local computer to the date and time saved in the
Set-Date -Adjust -0:10:0 -DisplayHint Time Example 3: Set the date and time to a variable value The DisplayHint parameter tells PowerShell to display only the time, but it does notĪffect the DateTime object that Set-Date returns. The Adjust parameter allows you to specify an interval of change (minus ten minutes) in the This example sets the current system time back by 10 minutes. Set-Date -Date (Get-Date).AddDays(3) Example 2: Set the system clock back 10 minutes The DateTime object'sĪddDays method adds a specified number of days ( 3) to the current DateTime object. The Get-Date cmdlet returns the current date as a DateTime object. Uses the Date parameter to specify the date. This command adds three days to the current system date. Examples Example 1: Add three days to the system date To specify a change interval, use the Adjust parameter. To specify a new date or time, use the Date parameter. You can specify a new date and/or time by typing a string or by passing a DateTime or The Set-Date cmdlet changes the system date and time on the computer to a date and time that you Changes the system time on the computer to a time that you specify.
