i’m building an android application which have a chat.
in this chat i each message to have its time sent signature.
my question is as follow:
lets say that the time in my country is X. my friend is abroad and his time is X minus 7 hours.
i’m sending him a message at 16:00 local time.
i want to avoid the situation that he will get at 09:00 a message which it signature will be 16:00 (which is a time in future if you’re looking in the eyes of that friend in his country).

is there a way that in my phone the message will be written as 16:00 and in his phone it will be written as 09:00 ? i there a way to convert a time to a local time ?

    Use a long to save your time information as milliseconds since “epoch” (which is January 1, 1970, 00:00:00 GMT). It can be retreived with the Date.getTime() method and new Date objects are easily created using the Date(long millis) constructor. The Date objects are then displayed using the local timezone settings on each device.

    EDIT:

    Epoch is a defined point in time which is expressed differently in different time zones: 1970-01-01 00:00:00 GMT but
    1969-12-31 19:00:00 EST. The timestamp is just the number of milliseconds elapsed since that time. So, for example the timestamp 1341169200 corresponds to 2012-07-01 19:00:00 GMT and 2012-07-01 14:00:00 EST.
