Top Forums Shell Programming and Scripting Convert UTC time into current UNIX sever time zone Post 302879311 by blackrageous on Wednesday 11th of December 2013 06:56:28 PM

This does seem to be a bit vague. Here is a useful tip and in this case I am using the korn shell. The idea here is to temporarily define the TZ environment variable; that is....
Code:
TZ=CDT date

would define the TZ var for the execution of the date command...regardless of what the default TZ setting is.

By example...
Code:
[josephgr@oc0887178221 ~]$ date; TZ=UTC date
Wed Dec 11 17:57:03 CST 2013
Wed Dec 11 23:57:03 UTC 2013

ftime(2)							System Calls Manual							  ftime(2)

NAME
ftime - get date and time more precisely SYNOPSIS
Remarks This facility is provided for backwards compatibility with Version 7 systems. Either or should be used in new programs. DESCRIPTION
fills in a structure pointed to by its argument, as defined by /* * Structure returned by ftime system call */ struct timeb { time_t time; unsigned short millitm; short timezone; short dstflag; }; The structure contains the time in seconds since 00:00:00 UTC (Coordinated Universal Time), January 1, 1970, up to 1000 milliseconds of more-precise interval, the local timezone (measured in minutes of time westward from UTC), and a flag that, if nonzero, indicates that Day- light Saving time applies locally during the appropriate part of the year. Consult gettimeofday(2) for more details on the meaning of the timezone field. can fail for exactly the same reasons as gettimeofday(2). WARNINGS
The millisecond value usually has a granularity greater than one due to the resolution of the system clock. Depending on any granularity (particularly a granularity of one) renders code non-portable. SEE ALSO
date(1), gettimeofday(2), stime(2), time(2), ctime(3C). STANDARDS CONFORMANCE
ftime(2)
All times are GMT -4. The time now is 12:33 PM.
