如何统计两个时点的时间差

答：
说明，adtm_start和adtm_end分别是你要比较的日期
long ll_total_seconds, ll_day_adjust
date ld_sdate, ld_edate
time lt_stime, lt_etime

ld_sdate = date(adtm_start)
ld_edate = date(adtm_end)

lt_stime = time(adtm_start)
lt_etime = time(adtm_end)

//86400为一天的总秒数
If ld_sdate = ld_edate then
ll_total_seconds = secondsafter( lt_stime,lt_etime)
Elseif ld_sdate < ld_edate Then
ll_total_seconds = SecondsAfter(lt_stime,Time('23:59:59'))
ll_day_adjust = DaysAfter(ld_sdate,ld_edate) -1
If ll_day_adjust > 0 Then ll_total_seconds = ll_total_seconds + 86400 * ll_day_adjust
ll_total_seconds = ll_total_seconds + SecondsAfter(Time('00:00:00'),lt_etime) +1
Else //end date < start date
ll_total_seconds = SecondsAfter(lt_stime,Time('00:00:00'))
ll_day_adjust = DaysAfter(ld_sdate,ld_edate) +1
If ll_day_adjust < 0 Then ll_total_seconds = ll_total_seconds + 86400 * ll_day_adjust
ll_total_seconds = ll_total_seconds + SecondsAfter(Time('23:59:59'),lt_etime) -1
end If

ll_total_seconds就是最终的秒数的差，然后除以3600就是小时了。OK、
