Remaining days to a date is not showing correctly

由 大兔子大兔子 提交于 2019-12-12 18:37:48
问题 Ok, so I've created a function to show the number of days until a date in the future... It is correct until the amount of days is over 9 days.. if over it seems to show a random number of days... Please see my code below: public String daysTillExpire() { String daysLeft = ""; int position = 0 ; String inputDateString = UIDM.get(position).date; Calendar calCurr = Calendar.getInstance(); Calendar day = Calendar.getInstance(); try { day.setTime(new SimpleDateFormat("dd-MM-yyyy").parse

calendar start date before end date on same day difference

问题 I have two calendar dates where i am getting the difference between in days, hours, and minutes. This works perfectly if the end date is greater than the start date. What doesnt work is if the start date is the same day of week as the end date, but an earlier time than the end date. For example: end date 2:20 pm Saturday, and start date is 7:20 pm on saturday. It calculates it at like 0days, and 5 hours. But, it should be more like 7 days. Here is the code long t1 = curCal.getTimeInMillis();

Comparing two date objects of different TimeZones and get the exact time difference in seconds

由 社会主义新天地 提交于 2019-12-11 03:06:12
问题 I am trying to compare received date of an email(date object) with a date(String) in a JSONObject. The two dates are going to be of different Timezones with a difference of 1 hour. My scenario is that I'll have to get the exact difference between them in seconds and if the difference is +/- 10 seconds, I would have found a match. For this purpose, I decided to convert the both into 'UTC' and then do a difference. Here is my code: SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm

There are several programs showing the date difference but all have dates

问题 I wonder if anyone has seen this, and if there is a solution, or if I'm just not doing something right. I'm trying to get the hours difference between now and a "created date" in a database record - not trying to get the total hours, but the hours left after you get rid of total days, so you can output that something is x days, x hours old. Initial Givens Let's use a SYSDATE , or "now", of 12/6/2016 6:41 PM . Let's say I have an Oracle table and a SQLite table that we will call MyTable . In

问题 How to find the number of days between two days not dates using PHP? I know how to get the number of days between two dates, but my input values are day names (date-ignorant). Inputs/Outputs: Wednesday and Saturday returns 3 Sunday and Wednesday returns 3 回答1: Your task doesn't seem to require date functions at all. A simple lookup array will suffice. Subtract the starting day's integer value from the ending day's integer. If the difference would be zero or less, add 7 to always return the
