Israel Standard Time (IST) and Israel Daylight Time (IDT) are 2 hours |
2102 |
ahead of the prime meridian in winter, springing forward an hour on |
2103 |
March's fourth Tuesday at 26:00 (i.e., 02:00 on the first Friday on or |
2104 |
after March 23), and falling back on October's last Sunday at 02:00. |

Western Argentina Summer Time (WARST) is 3 hours behind the prime |
2111 |
meridian all year. There is a dummy fall-back transition on December |
2112 |
31 at 25:00 daylight saving time (i.e., 24:00 standard time, |
2113 |
equivalent to January 1 at 00:00 standard time), and a simultaneous |
2114 |
spring-forward transition on January 1 at 00:00 standard time, so |
2115 |
daylight saving time is in effect all year and the initial @code{WART} |
2116 |
is a placeholder. |
