Hi Sergey,
Here's the method() I use to calculate checksum

method myCheckSum()
  LPARAMETERS tt

  IF VARTYPE(tt) # 'T'
    tt = {}
  ENDIF

  LOCAL lc
  lc = SYS(2007,TRANSFORM(tt-60))
  RETURN lc

method mySetTime()
  lt = datetime()
  lc = this.myCheckSum(lt)
  replace myDateTime with lt, dt_check with lc

method myValidate_Time()
  return this.myCheckSum(myDateTime) # dt_check

for ctot("06/29/2003 11:01:39 PM")
Runtime version returns 46007
Development version returns 37964

If I run myValidate_Time() from the same version (Runtime or Development) that mySetTime() was run it returns .t., but if I run them from different versions it returns .f.
