    Ok, everyone who’s ever had to use datetime hates it, but not because it’s insufficient, but because international date/time is such a nightmare that the library must be complicated enough to support all the edge cases I’m convinced that library has a function for traveling trough time.

    For years I’ve wrapped datetime with custom functions that do exactly and only what I want to mitigate its all-plumbing-zero-porcelain approach to the problem.

        This is exactly why I love PowerShell.

        Need the [DateTime] object from 10 years ago? No biggie, just chuck (Get-Date).AddYears(-10) down your console.

        Need it in a specific timezone? That one’s trickier, but since PowerShell can do .Net, run this:

        $TargetDateTime = (Get-Date).AddYears(-10)
$TargetTimeZone = "India Standard Time"
$tz = [TimeZoneInfo]::FindSystemTimeZoneById($TargetTimeZone)
$utcOffset = $tz.GetUtcOffset($TargetDateTime)
[DateTimeOffset]::new($TargetDateTime.Ticks, $utcOffset)

        And you get a DateTimeOffset object, which is this beauty:

        DateTime           : 25/08/2015 23:15:14
UtcDateTime        : 25/08/2015 17:45:14
LocalDateTime      : 25/08/2015 19:45:14
Date               : 25/08/2015 00:00:00
Day                : 25
DayOfWeek          : Tuesday
DayOfYear          : 237
Hour               : 23
Millisecond        : 421
Microsecond        : 428
Nanosecond         : 600
Minute             : 15
Month              : 8
Offset             : 05:30:00
TotalOffsetMinutes : 330
Second             : 14
Ticks              : 635761413144214286
UtcTicks           : 635761215144214286
TimeOfDay          : 23:15:14.4214286
Year               : 2015

        DateTime is the time in your target timezone, UtcDateTime is, well, the UTC time, and LocalDateTime is the time on host you ran the commands on.

      Complicated or not, the interfaces suck. And dont have to. And that’s the problem.
