describe in details history of displays in there? how long ?
Your question could mean two things, so I'll cover both: how the displays have changed over time, and how much time they span. I only focus on the Archaeological Museum, because the Zeugma Mosaic Museum has a separate history.
History of the displays
Gaziantep began setting up its museums in 1944, and the Archaeology Museum on İstasyon Caddesi opened in 1969. Sources disagree on details. One account says the building was substantially enlarged in 2005 to house the newly discovered Zeugma mosaics, so the early displays were dominated by those floors.

As the mosaics and other finds filled the exhibition space, the mosaics were moved to their own Zeugma Mosaic Museum in 2011, and a redesign of the archaeology museum was announced. The enlarged, modernized halls reopened to the public on 18 May 2017. The present displays are therefore less than a decade old, though the collections behind them go back to the mid-20th century.

How much time the displays span
The museum covers a very long span. The displays run from the Lower Paleolithic to the early 20th century, in chronological order, starting on the ground floor. The route goes roughly like this:
ktb
Natural history and Paleolithic: The exhibition begins with fossils and rocks from past geological periods, then the natural history of Gaziantep and a display on the Lower Paleolithic. The extinct Maraş elephant skeleton belongs here. The museum has the skeletal remains of this animal on display.

Neolithic: Stone sculptures from the Neolithic age.
ktb
Chalcolithic and Early Bronze Age: Finds from Şaraga, Sakçagözü, Gedikli, Tilmen, Zincirli and Sam.
ktb
Late Hittite period: Artifacts from this important period, in particular from the ancient city of Carchemish (Karkamış).
ktb
Roman to Ottoman: Coins and clay seal impressions from Zeugma, plus finds from the Islamic and Ottoman periods. The Zeugma seal impressions are notable: they are described as the world's largest collection of clay seal impressions from the ancient city.

Outdoor garden: Stone artifacts including pagan and Christian tombstones from Zeugma and Hittite statuary.

That means one building runs from several hundred thousand years ago to about a century ago. This matches your timeline, but the museum's display of the Paleolithic section should be treated as showing the region's oldest human traces, not an exact dated sequence of the Dülük finds.
How long a visit takes
I could not find an official figure. As my own rough estimate, most visitors spend about 1.5 to 2 hours in the Archaeology Museum, and more if you read the labels closely. Opening hours and gallery arrangements can change, so check the museum's official page before you go.
I can also turn this into Chinese, or into a one-page visitor route if you'd like.
加济安泰普考古博物馆：展陈的历史与时间跨度
你的问题可以有两种理解，所以我两方面都讲：展陈随时间发生了哪些变化，以及展陈涵盖了多长的时间。这里只讲考古博物馆，因为宗伽玛马赛克博物馆有自己独立的历史。
展陈的历史
加济安泰普从1944年开始筹建博物馆，位于伊斯塔斯翁大街（İstasyon Caddesi）的考古博物馆于1969年对外开放。各来源在细节上并不一致。有一种说法称，这座建筑在2005年曾大幅扩建，用来安放新发现的宗伽玛马赛克，因此早期的展陈以这些地面马赛克为主。
随着马赛克和其他出土物越来越多，展厅空间不够用，2011年马赛克被转移到独立的宗伽玛马赛克博物馆，同时宣布对考古博物馆进行重新设计。扩建并现代化后的展厅于2017年5月18日重新向公众开放。因此，现在的展陈还不到十年，不过其背后的藏品可以追溯到20世纪中叶。
展陈涵盖的时间跨度
这座博物馆涵盖的时间非常长。展陈从旧石器时代早期一直延伸到20世纪初，按时间顺序排列，从底层开始。参观路线大致如下：
自然史与旧石器时代： 展览从过去地质时期的化石和岩石开始，接着是加济安泰普的自然史，以及介绍旧石器时代早期的展示。已灭绝的马拉什象（Maraş elephant）骨架也在这一部分。博物馆展出了这种动物的骨骼遗骸。
新石器时代： 新石器时代的石雕。
铜石并用时代和早期青铜时代： 来自沙拉加（Şaraga）、萨克恰格兹（Sakçagözü）、盖迪克利（Gedikli）、蒂尔门（Tilmen）、津吉尔利（Zincirli）和萨姆（Sam）的出土物。
晚期赫梯时期： 这一重要时期的文物，尤其是来自古城卡尔凯美什（Karkamış）的文物。
罗马时期至奥斯曼时期： 来自宗伽玛的钱币和泥印（印章压痕），以及伊斯兰和奥斯曼时期的出土物。宗伽玛的泥印尤其值得一提：据介绍，这里是世界上收藏这座古城泥印最多的地方。
室外花园： 石制文物，包括来自宗伽玛的异教和基督教墓碑，以及赫梯雕像。
也就是说，一座建筑里的展陈，从几十万年前一直走到大约一个世纪以前。这与你的时间线相符，不过旧石器部分应当理解为展示本地区最古老的人类遗迹，而不是对迪吕克（Dülük）出土物所作的精确断代序列。
往昔的碎片：加济安泰普考古博物馆
加济安泰普的博物馆把我们一路讲述的漫长故事集中在一座城市里，从燧石工具到罗马马赛克。这座城市周围分布着大量已发掘的遗址，因此馆藏直接来自周边的土地，而不是来自遥远的帝国。
加济安泰普考古博物馆是传统的参观起点。它的藏品按照本地区的时代序列展开：来自迪吕克（Dülük）等遗址的旧石器时代工具，新石器和铜石并用时代的遗物，来自蒂尔门土丘（Tilmen Höyük）等土丘的青铜时代出土物，以及赫梯和铁器时代世界的文物。来自新赫梯城邦的石浮雕和石碑，展现了卡尔凯美什（Karkamış）的卢维语象形文字传统。加济安泰普地区还有自己的赫梯雕刻作坊，位于伊斯拉希耶（İslahiye）附近的耶塞梅克（Yesemek），这是少数作坊本身得以保存下来的地方，采石场里还留着未完工的玄武岩狮子和斯芬克斯。
这座城市最著名的博物馆是2011年开放的宗伽玛马赛克博物馆（Zeugma Mosaic Museum）。宗伽玛是幼发拉底河畔的一座罗马边境城市，富人的别墅用彩色的地面马赛克装饰。21世纪初，比雷吉克水坝（Birecik Dam）上涨的水位威胁要淹没遗址的大部分。经过抢救性发掘和国际援助，许多马赛克得以保存，后来被运到加济安泰普。这座博物馆是同类博物馆中规模最大的之一，展出整间房屋的地面和壁画，主题有神话、宴饮和海洋。
其中最著名的作品是"吉普赛女孩"（Gypsy Girl），这是一幅年轻女子的马赛克肖像，有着大而直视前方的眼睛。这个名字只是一个通俗的昵称，学者们提出她可能代表某位神话人物。她已经成为加济安泰普的象征。另一件亮点是在宗伽玛发现的战神马尔斯（Mars）青铜像。描绘海神和英雄的大型马赛克，则展示了宗伽玛的上层人士如何把希腊神话带到幼发拉底河边境。
两座博物馆合在一起，体现了这座城市的特点。考古博物馆涵盖了深远的时间跨度，从旧石器时代的作坊到赫梯和铁器时代的国家，而宗伽玛马赛克博物馆则呈现了罗马时代一个辉煌的篇章。参观这两处，你可以在一天之内从最早的工具走到罗马帝国的边境，然后继续前往城堡和古老的集市，伊斯兰和突厥时期的城市就是从那里开始的。
