EO objects for date/time manipulations.

To get current time:

QQ.dt.now > t

To make time from absolute value in nano-seconds after Epoch:

QQ.dt.time > t
  1656855443000000000

This value represents July 3, 2022 at 13:37:23 UTC (2022-07-03T13:37:23Z).

To make short time interval:

QQ.dt.nanosecond.mul 10 > ten-ns
QQ.dt.microsecond.mul 50 > fifty-mcs
QQ.dt.millisecond.mul 100 > hundred-ms
QQ.dt.second.mul 3 > three-seconds
QQ.dt.minute.mul 4 > four-minutes
QQ.dt.hour.mul 5 > five-hours
QQ.dt.day > one-day
QQ.dt.week.mul 2 > two-weeks

To print it in ISO 8601 format using strftime:

QQ.io.stdout
  QQ.txt.sprintf
    "Current time is %s"
    QQ.dt.strftime
      "%Y-%m-%dT%H:%M:%S%z"
      t

To parse ISO 8601 back to time using strptime:

QQ.dt.strptime > t
  "%Y-%m-%dT%H:%M:%S%z"
  "2022-07-03T20:26:09+0300"

The object QQ.dt.time has the following attributes:

• plus adds two times
• minus subtracts
• eq compares
• gt is TRUE if greater than
• gte if greater than or equal
• lt if less than
• lte if less than or equal

For example, to add five hours and thirty minutes to the current time and then compare it with the time of file creation:

QQ.io.stdout
  if.
    gt.
      plus.
        QQ.dt.now
        QQ.dt.hour.mul 5
        QQ.dt.minute.mul 30
      utime.
        QQ.fs.file
          "test.txt"
    "The file is too old"
    "The file is fresh"

There are two objects that are aware of calendar specifics and must be used on the left side of the equation in order to respect the calendar. The following code will move current time three months ahead:

plus
  QQ.dt.month.mul 3
  QQ.dt.now
