Unix/Epoch Timestamp Conversions and even Usages (What?, The reason why?, How? )
What could be the Unix timestamp?
Unix timestamp is simply the number involving seconds/milliseconds elapsed given that 1970 Jan 1st to any certain instant of time.
For instance , the timestamp of 1970 Feb 1st, 1 was is 3600(because typically the time difference through 1970 Jan first, 1am to 70 Jan 1st is 3600 seconds).
---------------------------- About 32-bit and even 64-bit systems with regard to timestamps ----------------------------
convert to time
Handful of systems still retail store timestamps as an agreed upon 32-bit integer, individuals services can cause difficulties from January 20, 2038. This issue is recognized as the Yr 2038 problem Or perhaps Y2038. Storing the particular timestamp as a new 64-bit integer can be more future-proof for that long-term support.
Timestamps can become represented in multiple forms: seconds, milliseconds, and nano-seconds.
Second timestamp - This particular timestamp represents the count of just a few seconds.
Milli-seconds timestamp -- This timestamp represents the count associated with milliseconds.
Nano-seconds timestamp - This timestamp represents the count of nano-seconds.
Precisely why Unix timestamp is definitely needed?
Unix/Epoch timestamp gives an exclusive representation of the particular date-time around globally. It always presents the date-time in GMT (Greenwich Result in Time Zone) or even UTC, then the date-time of different timezone will be received by having or subtracting time difference between the timezone in addition to GMT.
While doing work with date-time working with timestamps in typically the coding language and storing them within the database would certainly be the best approach as they will be generic for all the particular timezones. Date-time string signifies merely one particular timezone, so possessing a timestamp will be very easy to level the application to work users worldwide.
The particular other alternative regarding timestamps to include in coding is ISO-String, nevertheless even the Iso-strings are generic for the timezones. The conversion of the particular date string to a new different timezone is just not as simple since converting the timestamp.
For instance , If typically the timestamp value is usually 1577923200 then,
With GMT, enough time is Thurs night, January 2nd 2020, 00: 00: 00 GMT+00: 00
At India/Kolkata, the time is Thursday, Present cards 2nd 2020, 05: 30: 00 GMT+05: 30
At America/New_York, the time is Wednesday, January 1st 2020, 19: 00: 00 GMT-5: 00
How Unix timestamp conversion is performed?
The epoch variation between the given day plus the date 1970 Jan 1st will certainly give the timestamp value.
From the received timestamp value, a person should add or subtract the counter value of your own timezone from the particular timestamp to find the exact timestamp to the presented date.
