 | | The timezone variable contains the difference, in seconds, between UTC and local standard time; the altzone variable contains the difference, in seconds, between UTC and the alternate time zone (DST). The daylight variable is non-zero if DST is in effect, zero otherwise. The tzname array contains the names (abbreviations) of the time zones for local standard time and DST; for example, in New York City tzname[0] contains EST and tzname[1] contains EDT. Prior to calling tzset, these four variables contain values that describe Coordinated Universal Time. | |
