tomorrow's date

VWR Admin — Tue, 11 Mar 2003 16:54:13 GMT

how can I display tomorrow's date? I'm sure this was asked for before. In fact I'm sure I did it before but yesterday's are gone from my memory! Thanks,

Do a search thru the Forums and look for A. Clay Stephenson's caljd.sh or caljd.pl script.

Or for Europian sites :

TOMORROW=`TZ=$TZ-24 date '+%Y/%m/%d'`

The use of the following is commonly seen to compute tomorrow's date:

# TZ=GMT-24 date +%m/%d/%y

...and "correspondingly", yesterdays's date"

# TZ=GMT+24 date +%m/%d/%y

Eurpopeans,living around the Prime Meridian are the "lucky" ones who can use +-24 hours to exactly compute yesterday or tommorrow *including* the correct time.

As noted by the man pages for environ(5), the offset is the value that must be added to local time to arrive at UTC (GMT). The offset takes the format hh[:mm[:ss]] where(hh)is any value from 0 through 23. The optional minutes (mm) and seconds (ss) fields are a value from 0 through 59. The hour field is required. If offset is preceded by a -, the time zone is east of the Prime Meridian. A + preceding offset indicates that the time is one that is west of the Prime Meridian.

For example, it is now about 1221 hours on March 11 in the Eastern US. To produce a date *and time* exactly 24-hours from now, I would need to compute an offset of (24-5) to account for the difference in my timezone (EST) and UTC time.

Notice that I cannot produce an exact date and time for yesterday, however, since to affect this, the computation would need to offset 29 hours (24+5), an invalid offset.

You are advised to beware.
