Tomorrow

Function Tomorrow: TDateTime

Example​

procedure ScriptEvent(var Value: variant);
begin
  Value := Tomorrow;
end;

Usage​

Tomorrow returns the Windows host's next local calendar date at midnight.

Returns

The host's next local date at 00:00:00.000 as an untagged TDateTime.

Behaviour

  • A call made on 18 July returns midnight at the start of 19 July according to the host calendar.
  • The result changes when the host-local date crosses midnight.
  • Adding a whole encoded day avoids daylight-saving elapsed-time arithmetic; the function returns a calendar date without a timezone tag.

Important usage notes

  • The value comes from the Velox host, not a client workstation, source document or trading partner timezone.
  • Two calls around local midnight can return different dates. Capture one result when a flow requires a stable processing date.
  • The function does not attach a timezone or UTC marker. Formatting or later conversion depends on the surrounding convention.
  • It is equivalent to Date + 1, not Now + 1: the time portion is always zero.

Errors

No normal application error is expected. Operating-system clock availability and invalid host state are not handled by a Velox function.

Additional Technical Info​

Tomorrow returns the calendar date immediately after the Windows host's current local date. The result is midnight at the start of that next day, not the current time plus 24 elapsed hours.

The example is environment-dependent and source-reviewed. It was not executed by the documentation workflow.

Implementation

The DateUtils scripting import binds directly to Delphi 37.0 System.DateUtils.Tomorrow. The terminal calls System.SysUtils.Date to take one local Windows date snapshot and adds one whole encoded day.

Side effects

Reads the host's local system date. It does not change the clock or persistent state.

Performance and concurrency

Constant-time with one host-clock read. It is re-entrant, but results can differ across a midnight or concurrent host clock/timezone change.
