GetDateInt4 Subroutine

public subroutine GetDateInt4(yyyymmdd_1, hhmmss_1, offset, yyyymmdd_2, hhmmss_2, rc)

GetDateInt4 — Returns a new date/time from an initial date/time and offset

This subroutine returns a new date and time in yyyymmdd and hhmmss format given and initial date, time, and offset in seconds. The routine converts the input date and time to julian seconds, adds the offset, and converts back to yyyymmdd and hhmmss format. This routine has been tested for Y2K compiance.

History

  • 1998.07.20 Lucchesi Initial version.
  • 2010.05.11 Lucchesi Integer for julian seconds changed to 64-bit. StartDate constant no longer needed.

Arguments

Type IntentOptional Attributes Name

Initial time in HHMMSS format
integer :: offset

Offset to add (in seconds)
integer :: yyyymmdd_2

New date in YYYYMMDD format
integer :: hhmmss_2

New time in HHMMSS format
integer :: rc

Return code. (<0 = error)
